A 0.42 kg soccer ball is moving down field with a velocity of 12 m/s. A player kicks the ball so that it has a final velocity of

18 m/s down field. What is the change in the balls momentum? and find the constant force exerted by the players foot on the ball if the two are in contact for 0.020 s?

Answer:

the change in momentum is 2.52 N·s

the constant force on the ball while in contact with the players foot is 126 N

Explanation:

p=momentum

m=mass

v=change in velocity

p=(0.42)(6)

p=2.52

An what would be needed to change an objects state of motion
VladimirAG [237]

Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.

Kay [80]

Answer:

4.93 m

Explanation:

According to the question, the computation of the height is shown below:

But before that first we need to find out the speed which is shown below:

As we know that

Speed = \frac{Distance}{Time}

Speed = \frac{5}{0.504}

= 9.92 m/s

Now

v^2 - u^2 = 2\times g\times h

9.92^2 = 2\times 9.98 \times h

98.4064 = 19.96 × height

So, the height is 4.93 m

We simply applied the above formulas so that the height i.e H could arrive

sveta [45]

Answer:

Ultraviolet wave

Explanation:

Ultraviolet waves would be best used to sterilize a surface expose to bacteria because it will completely destroy them.

Most medical equipment are usually sanitized by using this rays because the DNA of most bacteria can be innervated upon exposure to these ray.

Ultraviolet rays are energetic and more powerful than the normal visible light and subsequent long wavelength radiations.

Generally, ultraviolet rays is a very harmful electromagnetic radiation.
