Question

A lead ball strikes a wall and falls down, a tennis ball having the same mass and velocity strikes the wall and bounces back. Check the correct statement.
A. The momentum of the lead ball is greater than that of the tennis ball
B. The lead ball suffers a greater change in momentum compared with the tennis ball
C. The tennis ball suffers a greater change in momentum compared with the lead ball
D. Both suffer an equal change in momentum

Answer 1

Hint: Before entering the question you should know one thing, the lead ball is made up of leaders of some kind of alloy metal, which means it is fully made up of solid or it is fully made up of metal. But the tennis ball has more elasticity compared to the lead ball. So the tennis ball has a greater change in momentum.

Complete step by step solution:
The tennis ball is mostly made up of nylon. So the nylon is an elastic synthetic polymer with a protein-like chemical structure. It is sometimes used in the shells of tennis balls. Naturally, nylon has a high elasticity in nature. If we strike a tennis ball into the wall means, it has a high change in momentum to compare other materials (like metals, solid, etc.,)
The tennis ball has a greater change in momentum because it has a high elasticity. If we strike a tennis ball into the wall, it suffers a greater change in momentum compared to a lead ball.
So the option (C) is correct.

Additional Information:
Let us consider the other options:
Option (A)
From the question, we know both tennis balls and lead balls have the same mass and same velocity. The momentum is a multiplication of mass and velocity. So the lead ball and tennis ball have the same momentum. So option (A) is wrong.
Option (B)
We know the tennis ball is made up of lead or lead mixed metal alloys. So it is fully made up of solid. The metal kind of solid objects didn’t have a high change in momentum. So the option (B) is wrong.
Option (D)
The tennis ball has more elasticity compared to the lead ball. The tennis ball has a high change in momentum compared to a lead ball. It doesn’t have an equal change in momentum. So the option (D) is wrong

Note:
The change in momentum is also called an impulse. The principles of momentum control the mechanics of collisions. A collision occurs when an item is subjected to a force for some time, resulting in a change in momentum. The object's mass either speeds up or slows down as a result of the force acting during the specified amount of time (or changes direction). The change in momentum of the item is equal to the object's impulse.
