A metal ball hits a wall and does not rebound whereas a rubber ball of the same mass on hitting the wall the same velocity rebounds back. It can be concluded that -a)metal ball sufferes greater change in momentumb)rubber ball suffers greater change in momentumc)the initial momentum of metal ball is greater than the initial momentum of rubber balld)both suffer same change in momentumCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Because in equation metal ball doesn't rebound and rubber ball of ame mass rebounds so rubber ball has change in momentum twice or less than twice of metal ball.
mv-(-nmv)=(n+1)mv, 0< /><1.>

Answer

Because when the body of rubber ball hit the wall all the charge of ball is repel each other and and show their elasticity but a metal ball does not

Answer

Explanation:

When a ball hits a wall, it experiences a change in momentum. Momentum is defined as the product of an object's mass and its velocity. The change in momentum can be determined by subtracting the initial momentum from the final momentum.

Initial Momentum:
The initial momentum of an object is given by the product of its mass and velocity before the collision. In this case, both the metal ball and the rubber ball have the same mass and the same velocity before hitting the wall. Therefore, the initial momentum of both balls is the same.

Final Momentum:
The final momentum of an object is given by the product of its mass and velocity after the collision. In the case of the metal ball, it does not rebound after hitting the wall, so its velocity after the collision is zero. Therefore, the final momentum of the metal ball is zero.

On the other hand, the rubber ball rebounds after hitting the wall, so its velocity after the collision is in the opposite direction to its initial velocity. This means that the final velocity of the rubber ball has the same magnitude as its initial velocity but in the opposite direction. Therefore, the final momentum of the rubber ball is equal to the initial momentum but in the opposite direction.

Change in Momentum:
The change in momentum can be determined by subtracting the initial momentum from the final momentum. In the case of the metal ball, the change in momentum is equal to the final momentum (which is zero) minus the initial momentum (which is the same as the final momentum). Therefore, the change in momentum for the metal ball is zero.

In the case of the rubber ball, the change in momentum is equal to the final momentum (which is the negative of the initial momentum) minus the initial momentum. Therefore, the change in momentum for the rubber ball is twice the initial momentum in magnitude but in the opposite direction.

Conclusion:
From the above analysis, we can conclude that the rubber ball suffers a greater change in momentum compared to the metal ball. Therefore, option B is the correct answer.
