A 1.11 kg ball sits at rest on a table 1.72 m above the ground. What is the potential energy of the ball?

Answers

Answer:

18.71 joules

Explanation:

The formula to solve for potential energy is PE = mgh

where m = mass, g = force of gravity, and h = height.

m = 1.11 kg

g = 9.8 m/s^2

h = 1.72 meters

PE = (1.11)(9.8)(1.72)

PE = 18.71016

Therefore, the potential energy of the ball is 18.71 joules.

Answer:

The formula to solve for potential energy is PE = mgh

where m = mass, g = force of gravity, and h = height.

m = 1.11 kg

g = 9.8 m/s^2

h = 1.72 meters

PE = (1.11)(9.8)(1.72)

PE = 18.71016

Therefore, the potential energy of the ball is 18.71 joules.

when the weight of the object increase block what is the force of friction applied? Explanation?

Answers

Answer:

There is absolutely No relationship between the weight of an object (which is constant) and the frictional force. If a block is sliding on a surface, that surface will be exerting a force on the block. That force can be resolved into a component parallel to the surface (which we call the frictional component), and a component perpendicular to the surface (called the normal component). For many situations, we find experimentally that the frictional component is approximately proportional to the normal component. The frictional component divided by the normal component is defined to be a quantity called the coefficient of kinetic or sliding friction. The coefficient of kinetic friction obviously depends on the nature of the surfaces involved. The normal component on an object can be decreased if you pull in the direction of the normal component (the weight does not change). However pulling this way on the object not only decreases the normal component, but it also decreases the frictional component since they are proportional. This is why it is easier to slide something if you pull up on it while you push it. If you push down, the normal and frictional components increase so it is harder to slide the object. The weight of an object is the downward force exerted by Earth’s gravity on that object, and it does not change no matter how you push or pull on the object.

Conservation of Momentum
No one likes you little trolls please send an actual answer

Answers

Hello!

This is an example of an inelastic collision, where the two objects "stick" to each other after their collision. (The Goalkeeper CATCHES the puck).

We can write out the conservation of momentum formula:

m1vi + m2vi = m1vf + m2vf

Let:

m1 = mass of puck

m2 = mass of the goalkeeper

We know that the initial velocity of the goalkeeper is 0, so:

m1vi + m2(0) = m1vf + m2vf

m1vi = m1vf + m2vf

The final velocities will be the same, so:

m1vi = (m1 + m2)vf

Plug in the given values:

(0.16)(40)/ (0.16 + 120) = vf ≈ 0.0533 m/s

Using the equation for momentum:

p = mv

The object with the LARGER mass will have the greater momentum. Thus, the Goalkeeper has the largest momentum as p = mv; a greater mass correlates to a greater momentum since the velocity is the same between the two objects. The puck would have a momentum of p = (.16)(0.0533) = 0.008528 kgm/s, whereas the goalkeeper would have a momentum of

p =  (120)(0.0533) = 6.396 kgm/s.

Students are given the following information about a 2.0 kg, motorized toy boat on water. what net force is exerted on the boat from 4S to 8S?

Answers

The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.

The motorized toy boat moves at 8 m/s (u) at 4 s and at 8 m/s (v) at 8 s. We can calculate the acceleration (a) in that period using the following kinematic expression.

[tex]a = \frac{v-u}{\Delta t} = \frac{8m/s-8m/s}{8s-4s} = 0 m/s^{2}[/tex]

The object with a mass (m) of 2.0 kg experiences an acceleration of 0 m/s². We can calculate the net force (F) in that period using Newton's second law of motion.

[tex]F = m \times a = 2.0 kg \times 0 m/s^{2} = 0 N[/tex]

The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.

What is the mass of an object if it accelerates at 3 m/s? and has a force of
1 N?

Answers

Answer:

1 / 3 or 0.33

that is if you meant that the object accelerates at 3 m / s² not 3 m / s

for the unit of acceleration is m / s²

Explanation:

m = ?

a = 3

f = 1N

where;

m = mass ( kg )

a = acceleration ( m / s² )

f = force ( N )

from all the parameters we are given, we can use Newton's second law of motion to solve it

that is;

a = f / m

to make m the subject of the formula, we have to cross multiply to give us;

m( a ) = f

divide through by a to give us;

m ( a ) / a = f / a

therefore,

m = f / a

so, we substitute our values to give us;

m = 1 / 3

therefore. m = 1 / 3 or 0. 33

bus slows down uniformly from 21 m/s to 0 m/s in 21 s. How far does it travel before stopping?

75 km/hour = (75,000/3,600) m/s =  20-5/6 m/s

The average speed of the bus while it slows down is

                                   (1/2)(20-5/6 + 0) = 10-5/12 m/s .

Traveling at an average of 10-5/12 m/s for 21 seconds,

What is the density of the football in g/cm

Answers

Answer:   see below.

Explanation:

Your question is lacking the necessary parameters, so I will assume the values to enable me to solve it:

Mass of football = 20 grams

Volume of football = 100[tex]cm^{3}[/tex]

To find the density of the football;

Density is simply mass per unit volume of an object such as a football.

Mathematically, the density of an object is given by the formula;

Density=[tex]\frac{Mass}{Volume}[/tex]

Substituting the assumed values into the above formula;

Density=[tex]\frac{20}{100}[/tex]

Density= 0.2g/[tex]cm^{3}[/tex]

Therefore, the density of the football is     0.2g/[tex]cm^{3}[/tex] .

For you: You can substitute the appropriate parameters into the formula to get the exact density of the ball.
