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

The momentum of the lead ball is greater than that of the tennis ball

The lead ball suffers a greater change in momentum compared with the tennis ball

The tennis ball suffers a greater change in momentum as compared with the lead ball

Both suffer an equal change in momentum

Text Solution

Verified by Experts

The correct Answer is:

Change in momentum `= P_f -P_i`
For lead ball `-DeltaP = 0 - mv - mv`
For tennis ball `-DeltaP =-mv - mv = -2mv`
