The bob A of a simple pendulum is released when the string makes an angle of 45° with the vertical. It hits another bob B of the same material and same mass kept at rest on the table. If the collision is elastic

Q: The bob A of a simple pendulum is released when the string makes an angle of 45° with the vertical. It hits another bob B of the same material and same mass kept at rest on the table. If the collision is elastic

(a) Both A and B rise to the same height

(b) Both A and B come to rest at B

(c) Both A and B move with the same velocity of A

(d) A comes to rest and B moves with the velocity of A

Ans: (d)
