Two identical balls A and B are released from the position shown in Fig. They collide elastically with each other on the horizontal portion. The ratio of heights attained by A and B after collision is (neglect friction)

An object initially at rest explodes into three fragments A B and C. The momentum of A is piˆ and that of B is 3–√p jˆ where p is a + ve number. The momentum of C will be
