Work Energy And Power Question 117
Question: The bob A of a simple pendulum is released when the string makes an angle of $ 45^{o} $ 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 [Kerala (Engg.) 2001]
Options:
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
Show Answer
Answer:
Correct Answer: D
Solution:
Due to the same mass of A and B as well as due to elastic collision velocities of spheres get interchanged after the collision.
