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 as compared with the lead ball

D

Both suffer an equal change in momentum

Text Solution

Verified by Experts

The correct Answer is:
C
Change in momentum `= P_f -P_i`
For lead ball `-DeltaP = 0 - mv - mv`
For tennis ball `-DeltaP =-mv - mv = -2mv`
