A metal ball does not rebound when struck on a wall, whereas a rubber ball of same mass when thrown with the same velocity on the wall rebounds. From this it is inferred that change in momentum of rubber ball is more than that of metal ball. How?

    Same mass or same size?

    Umm...I actually kinda got it..... Final velocity of rubber ball will be greater than that of iron ball and hence the change in momentum for rubber ball will be greater. (Following the appropriate sign convention)

    Same size \(\approx\) Same mass

    A metal ball would be much denser, so I'd imagine a rubber of same mass being much bigger in size, not enough to approximate

    Yes, that's correct. Here we are considering balls of same mass
