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
Correct Answer: C
Solution :
Change in the momentum = Final momentum ? initial momentum For lead ball \[\Delta {{\vec{P}}_{\text{lead}}}=0-m\vec{v}=-m\vec{v}\] For tennis ball \[\Delta {{\vec{P}}_{\text{tennis}}}=-m\vec{v}-m\vec{v}=-2m\vec{v}\] i.e. tennis ball suffers a greater change in momentum.You need to login to perform this action.
