if a particle's speed increases by a factor of 5, by what factor does its kinetic energy change?

Answers

Answer 1

The kinetic energy would increase by a factor of 25.

The kinetic energy of a moving body is a function of its mass and the velocity with which it is traveling. It can be expressed by the formula:

KE=1/2mu²

This suggests that the kinetic energy a body has varies directly with mass and with the square of the velocity. With this knowledge, we can easily figure out how it changes when the speed is altered by a certain factor. Assuming that the initial speed of a body of mass m was u, the initial kinetic energy of the body would be:

KE = 1/2mu²

Now that the speed is increased by a factor of of 5, the final speed y would be equal to 5 times the initial speed u, such that v=5u. The kinetic energy of the body would then be:

KE = 1/2m²

KE = 1/2m(5u)

KE = 1/2m(252)

Pulling out 25 and replacing the expression for the initial kinetic energy:

KE = 25.1/2mu²

KE = 25KE

So, on increasing the velocity by a factor of 5, the kinetic energy would increase by a factor of 25.

What is kinetic energy

Kinetic energy is the energy possessed by an object caused by the force of motion. The term kinetic comes from the Greek, 'kinetikos', which means to move. Therefore, an object moving at a certain speed must have kinetic energy, while an object that is not moving does not have kinetic energy.

Kinetic energy is also called motion energy, where the movement of an object can produce other energy. For example, motion energy can be turned into electrical energy, eventually that electrical energy can be utilized by humans.

Types of kinetic energy

Kinetic energy is divided into two types which are classified based on the movement of an object, namely:

Translational kinetic energy

This type of translation is kinetic energy produced by objects moving in a straight line with the same direction and speed. For example, a car driving on a highway and a bullet moving in a straight line.

Rotational kinetic energy

This is a condition when an object rotates. When rotating, the amount of energy in it can change. For example, the rotation of the earth around the sun, a spinning top that rotates on its axis, and a Ferris wheel.

a light truck can go around a flat curve of a 140 m radius with a speed of 26 m/s. what is the acceleration of the truck (in m/s2)

Answers

The acceleration of the light truck travelling around a flat curve with a radius of 140 m and a speed of 26 m/s is 17.14 m/s².

The acceleration of a light truck travelling around a flat curve with a radius of 140 m and a speed of 26 m/s can be calculated by using the equation: acceleration = (v2/r).

In this equation, ‘v’ is the speed of the truck, and ‘r’ is the radius of the curve.

Therefore, when substituting these values into the equation, we get: acceleration

= (262/140)

= 17.14 m/s².

Describe how transferring energy into the container affected the speed of the marbles.

Answers

The speed changes as a result of the energy being transferred into a container filled with magnetic marbles and the kinetic energy produced by the container's gentle shaking. Phase shifts will result from this.

The energy of a system changes together with each phase change it undergoes. These involve kinetic energy transmission to a system. Endothermic reactions occur when a condition changes from being more ordered to being less ordered. Exothermic reactions are always involved in transitions from one state to another that is more organised.

When a substance transforms from one state to another, a phase change occurs in the system. When the system receives enough energy or loses enough energy, these changes take place. Phase changes also happen when the system's pressure is altered.

The square of the separation distance is inversely correlated with the electrostatic force. F is therefore nine times smaller, or one-ninth the original value, if d is three times larger.

Coulomb's Law states that the force exerted between two charged objects is inversely related to their square of distance. As a result, if the distance is tripled, the force will be nine times weaker. The force between two charges is inversely proportional to the square of the distance between them and directly proportional to the product of the charges.

two people apply the same force from the same height to throw two identical balls in the air. will the balls necessarily travel the same distance? why or why not?

Answers

The gravitational force acting on the balls is different, so they won't necessarily move the same distance.

Everything falls at the same rate due to gravity. This explains why balls of different weights strike the ground simultaneously. The force acting downward is gravity, whereas the force acting upward is air resistance. The pull that is designated as tension is in that direction. As a result, the tension will point toward the string or rope and away from the mass. When a mass is hanging, the string pulls it upward, applying an upper force, which causes the tension to be on the upper side.

The new velocity of the 0.18 kg ball, given that it's initial velocity was 0.39 m/s is 0.37 m/s

How do I determine the velocity of the 0.18 kg ball after collision?

Mass of first ball (m₁) = 0.18 KgInitial velocity of first ball (u₁) = 0.39 m/sMass of second ball (m₂) = 0.016 KgInitial velocity of second ball (u₂) = 0.05 m/sNew velocity of second (v₂) = 0.26 m/sNew velocity of first ball (v) = ?

The new velocity of the first ball (0.18 Kg) can be obtained as follow:

Momentum before = Momentum after

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(0.18 × 0.39) + (0.016 × 0.05) = (0.18 × v₁) + (0.016 × 0.26)

0.0702 + 0.0008 = 0.18v₁ + 0.00416

Collect like terms

0.18v₁ = 0.0702 + 0.0008 - 0.00416

0.18v₁ = 0.06684

Divide both sides by 0.18

v₁ = 0.06684 / 0.18

M the mass of the earth and,

R is the radius of the earth.

Now if the radius of the earth is kept constant and mass of the earth is doubled.

The value of the new acceleration due to gravity will become,

g' = G2M/r²

Putting GM/r² = g,

ocko the clown (who has a mass of 60 kg) is standing still at the center of the ice rink when his rival bozo throws a 7 kg bowling ball in his direction at 10 m/s. assuming jocko catches the ball, how much energy is lost in the collision?

Answers

Assuming Jocko the clown (mass of 60kg) catches the 7kg bowling ball, which thrown into his direction at 10m/s, the energy that will lost in the collision is 313J (based on Conservation of momentum).

How to calculate the energy that will lost in collision based on conservation of momentum?

Conservation of momentum is a major law of physics which states that the momentum of a system is constant if no external forces are acting on the system.

Based from the question given :
m₁ (mass of jocko) = 60kg

v₁ (initial speed of jocko) = 0 m/s

m₂ (mass of bowling ball) = 7kg

v₂ (initial speed of bowling ball) = 10 m/s

Now let's use the conservation of momentum formula

m₁ * v₁ + m₂ * v₂ = (m₁ + m₂) * V

60 * 0 + 7 * 10 = (60 + 7) * V

V = 70 / 67 m/s

Energy lost = Kinetic energy initial (bowling ball) - Kinetic energy final

= 1/2 * m₂ * v₂² - 1/2 (m₁ + m₂) * V²

= 1/2 * ((7 * 10²) - (67 * (70/67)²))

= 1/2 * 626.86

= 313.43J

=313J (rounded)

Therefore, energy that lost in the collision is 313J.

a waterskier skis over the ramp shown in the figure at a speed of 30 ftys. how fast is she rising as she leaves the ramp?

Answers

A waterskier skis over the ramp shown in the figure at a speed of 30 ft/s, 7.73 ft/sec is rising as she leaves the ramp.

We assume the hypotenues = h

From the given figure (attached) ;

h² = x² + y²

Put the  values of x and y from the figure

h² = 15² + 4²

h² = 225 + 16

h² = 241

Take under root on both sides

h = √241

From the figure the value of sin∅ = 4/h

Put value of h

sin∅ = 4 / √241

The rate at which she is rising = verticle velocity

The rate at which she is rising = 30sin∅

Put the value of sign∅

The rate at which she is rising = (30 * 4) / √241

The rate at which she is rising = 7.73 ft/sec

The missing figure is attached.

if the strings are made of the same material, how would you expect the diameters of the lowest and highest strings to compare?

Answers

The correct option is B) [tex]d_{low} = 4d_{high}[/tex].The diameter of the lowest string is four times that of the highest string.

Because frequency is inversely proportional to the square root of mass density, the low string's mass density would be 16 times greater. The radius would increase by 4 times as a result.

If the diameter is same, the mass is same and the speed is 1/4 times due to the square root sign in the denominator. The frequency is 1/4 times because the wavelength is constant.

The relationship between frequency and diameter of a string is given by,

[tex]f=\frac{1}{L*d} \sqrt{\frac{4T}{\rho \pi}}[/tex]

Where,

L = length of the string

d= diameter of the string

T= tension of the string

[tex]\rho[/tex] = density of the string

Given, that the lengths of the strings are same; tension of the strings are same and as the string are of same material then the density of the strings are also same.

Thus, the frequency is inversely proportional to the string diameter.

f  = 1/d

So, if

[tex]4f_{low} = f_{high}[/tex]

Then,

[tex]d_{low} = 4d_{high}[/tex]

Thus,the diameter of lowest string is 4 times the diameter of highest string.

bert and ernie are pushing on opposite sides of the box. if they can both push with the same amount of force, what is true about the motion of the box?

Answers

The box will be in rest due to net force applied on it is zero.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

Given that Bert and Ernie are pushing on opposite sides of the box with force of same magnitude, let it be F.

So, net force acting om the force = F-F = 0.

As that net force acting on the box is zero, the box will be in rest.

Answers

The fraction of the neutron's kinetic energy transferred to the atomic nucleus is 2.05

If the initial kinetic energy of the neutron is

4.2 × 10−13 J, its final kinetic energy  will be 2.50 joules

What is kinetic energy?

kinetic energy of an object is described as the energy that it possesses due to its motion which is also the work needed to accelerate a body of a given mass from rest to its stated velocity.

In elastic head-on collision, the energy of the system and total momentum is conserved.

For the neutron,

m - mass

Vi - initial velocity

Vf - final velocity

For the atom ,

M- mass

Mi - initial velocity

Mf - final velocity

Conserved momentum on the head-on collision

mvi = mvf + MVF

vi - vf = MmVf

Vi- vf = 11.1 vf...... (i)

The kinetic energy is

Vi²- vf² = 11.1 v²f.......(ii)

Combining both equations

Vi + Vf = Vf

Solve equation (I) and (III) for Vi

vi = 5.4vf

Now, the fraction of the neutron's kinetic energy transferred to the atomic nucleus,

1/2 mv²f/ 1/2 mv²i = 11.1/ 5.4

If the initial kinetic energy of the neutron is

4.2 × 10−13 J, its final kinetic energy  will be 2.50 joules

Hence, we can conclude that the fraction of the neutron's kinetic energy transferred to the atomic nucleus is 2.05

The quantity of energy transferred or transformed per unit of time is known as power. It is a mechanically accepted quantity. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings. A scalar quantity is power. Power is related to other factors; for instance, the power required to move a ground vehicle is equal to the product of the vehicle's velocity, traction force on its wheels, and aerodynamic drag. A motor's output power is calculated by multiplying its torque output by the angular velocity of its output shaft. Energy divided by time represents the dimension of power. The watt (W), which equates to one joule per second, is the unit of power in the International System of Units (SI). Another popular unit of measurement is horsepower (hp), which is equivalent to a horse's power; one mechanical horsepower is equal to around 745.7 watts. Ergs per second (erg/s), foot-pounds per minute (fpm), dBm (a logarithmic measurement in relation to 1 milliwatt), calories per hour (cal/h), BTU per hour (BTU/h), and tons of refrigeration are other units of power.
