Answer:

Approximately [tex]9.9\; \rm m\cdot s^{-1}[/tex], assuming that this object started from rest, [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex], and that air resistance on this object is negligible.

Explanation:

If the effect of drag on this object is negligible, the acceleration of this object would be constantly equal to [tex]g[/tex], the gravitational field strength ([tex]g \approx 9.81\; \rm m\cdot s^{-2}[/tex] near the surface of the earth.)

Since acceleration is constant, it would be possible to find the final velocity of this object using SUVAT equations.

The following SUVAT equation would apply:

[tex]v^{2} - u^{2} = 2\, a\, x[/tex].

Rearrange to find an expression for [tex]v[/tex]:

[tex]\begin{aligned}v^{2} &= 2\, a\, x + u^{2}\end{aligned}[/tex].

[tex]\begin{aligned}v &= \sqrt{2\, a\, x + u^{2}}\end{aligned}[/tex].

Substitute in the values [tex]u = 0\; \rm m\cdot s^{-1}[/tex], [tex]a = 9.81\; \rm m\cdot s^{-2}[/tex], and [tex]x = 5\; \rm m[/tex]. Evaluate the expression to find the value of [tex]v[/tex]:

[tex]\begin{aligned}v &= \sqrt{2\, a\, x + u^{2}} \\ &= \sqrt{2 \times 9.81\; \rm m\cdot s^{-2} \times 5\; \rm m} \\ &\approx 9.9\; \rm m\cdot s^{-1}\end{aligned}[/tex].

Therefore, under these assumptions, the velocity of this object would be approximately [tex]9.9\; \rm m\cdot s^{-1}[/tex] right before it hits the ground.

Explanation:

let's use kinematics to solve for max height above the hand.

At the top of its arc, the sword has zero vertical velocity.

v² = u² + 2as

s = (v² - u²)/2a

s = (0² - 5.0²) / (2(-9.8))

s = 1.2755...m

call it 1.3 m

to this we must adjust for the height of the hand at release which is

18.0 + 1.0 = 19.0 m above ground

19.0 + 1.3 = 20.3 m above ground

Answer:4.38 X 10^10 diapers.

Explanation:

[3 diapers / 1day] X [365 day / year] X 1 year X 40million (rough guess of 1-2.5 year olds)  = 4.38 X 10^10 diapers.

if we assume that between birth and 2.5 y of age a child uses 3 diapers per day then the total number of disposable diapers used per year in us would be 1095 diapers

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis.

as given in the problem if we assume that between birth and 2.5 y of age a child uses 3 diapers per day

The number of diapers used in a day = 3

as there are 365 days in a year

The total number of diapers used in a year = 3×365

The total number of diapers used in a year = 1095 diapers

Thus, The total number of disposable diapers used in the United States each year would be 1095 diapers if we assume that a child uses 3 diapers per day between birth and 2.5 years of age.

Answer:

The cyclist rode the first 26​-mile portion of his workout at a constant speed.

Time = distance/speed

Time taken to ride through the first portion is

26/x

For the 18​-mile cool down portion of his​ workout, he reduced his speed by 4 miles per hour. It meas that his speed during the cool down portion is (x - 4) mph. Time taken to ride through the cool down portion is

18/(x - 4)

Since each portion of the workout took the same time, it means that

26/x = 18/(x - 4)

Cross multiplying, it becomes

26(x - 4) = 18x

26x - 104 = 18x

26x - 18x = 104

8x = 104

x = 104/8

x = 13 mph

His speed during the cool down portion is

13 - 4 = 9 mph

The defined friction force allows you to find which is the correct result for what type of wax you should use:

        B. One where the coefficient of static friction is larger.  

The friction force is a macroscopic force that opposes the relative movement of bodies, it is the sum of many interactions at the microscope level.

In general for solid bodies the expression of the out of friction is

             [tex]fr = \mu N[/tex]

Where fr is the friction force, μ the friction coefficient and N the normal.

The friction coefficient can be of two types:

In general, the dynamic coefficient is less than the static one.

In this case, as the temperature increases, the friction coefficient  decreases, so the skier begins to slide downwards. To prevent this sliding, he must use a wax with a higher friction coefficient.

If you only want to stand on the hill, a wax with a static coefficient must be used, while standing if you want to advance on the hill you must use a wax with a dynamic coefficient since there is a relative movement between the skier and the hill.

Let's examine the different alternatives:

A. False. The friction coefficient must be higher, so that there is more friction force.

B. True. The friction increases and can be stopped on the hill and move up the hill.

C. False In this case, you can go up the hill, but if you stop, you can go back.

D. False. The coefficient must be higher, to increase friction.

Consequently we see that the only type of wax that will allow you to stand or advance on the hill is

       B.  A wax with a higher statutory coefficient.

In conclusion, using the defined friction force we can find the correct result for what type of wax to use is:

         B. One where the coefficient of static friction is larger.

Explanation:

The center of mass of the two objects is the average position of the parts of the two object system

The center of mass of block A, and block B  after displacement of block B is at 20 m from block A

Reason:

The given parameters are;

The position of block A and block B at t = 0 is x = 0

The mass of block A, m₁ = 8 kg

Mass of block B, m₂ = 16 kg

Speed of block A = 0 m/s

Speed of block B, v₂ = 10 m/s

Location of the center of mass of the two object at t = 3 s; Required

Solution;

The location of block A, after 3 s is x₁ = 0 (block A is at rest)

The location of block B, = v₂ × t

The location of block B, after 3 s is x₂ = 10 m/s × 3 s = 30 m

The center of mass of two masses are given as follows;

[tex]x_{cm} = \dfrac{m_1 \cdot x_1 +m_2\cdot x_2}{m_1 + m_2}[/tex]

[tex]x_{cm} = \dfrac{8 \times0 + 16 \times 30}{8 + 16} = 20[/tex]

The center of mass of the two objects is at at the position x = 20 m (from block A)

Forces acting parallel to the ramp with UP RAMP being positive direction.

                                  F = ma

Tension minus weight minus friction will equal mass acceleration

Harry cycles 8 kilometers in 30 minutes and the Harry's average speed obtained is 6 kilometers per hour.

Given:

Total distance covered by the Harry= 8 kilometers

Total time is taken by the Harry= 30 minutes

Convert total time to hours, the total time taken is obtained as:

Total time (hours) = 30 minutes / 60 minutes/hour = 0.5 hours

The average speed of the Harry is given by:

Average speed = Total distance / Total time

Average speed = 8 km / 0.5 hours

Average speed = 16 km/h

Answer:

How Do Mass and Distance Affect the Force of Gravity Between Two Objects?  

The force of gravity between two objects is determined by the mass of each object and the distance between their centers. Objects with a greater amount of mass will exert a greater degree of gravitational pull, but as the distance between two objects increases, the gravitational force between them lessens.

Explanation:

An example of the significance of distance in Newton's law is how a person's weight decreases when they are further away from the center of the Earth, such as in an orbiting space station. The gravitational force, experienced as weight, is decreased, even through the person's mass and that of the Earth remain the same.

The surface area exists as the amount of space surrounding the outside of a three-dimensional shape.

The surface area of a solid object exists as a measure of the total area that the surface of the object settles.

The surface area of a figure (in square units) exists the number of unit squares it brings to cover the entire surface without gaps or overlaps. If a three-dimensional figure includes flat sides, the sides are named faces. The surface area exists as the total of the areas of the faces.

A radius of a circle or sphere exists in any of the line segments from its center to its perimeter, and in additional modern usage, it exists also its length.
