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 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
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
Change in the momentum
= Final momentum -initial momentum
For lead ball $\Delta {\vec P_{{\rm{lead}}}} = 0 - m\vec v = - m\vec v$
For tennis ball $\Delta {\vec P_{{\rm{tennis}}}} = - m\vec v - m\vec v = - 2m\vec v$
i.e. tennis ball suffers a greater change in momentum.
