8. A boy sitting in an open car moving with the constant speed throws a ball straight up into the air. The ball falls A.Behind him B.In front of him C.Into his hand D.By his side
Option A Solution: As per the question, the rubber ball rebounds while the metal ball does not. So if m and v be the mass and velocity respectively, the change in momentum of rubber ball = 2 mv (in magnitude). However, the change in momentum of the metal ball = mv. The rubber ball suffers almost twice the change in momentum as experienced by the metal ball.
