The bob A of a simple pendulum released ...

The bob A of a simple pendulum released from `30^(@)` to the vertical hits another bobo B of the same mass at rest on a table as shown in figure. How high does the bob A rise after the collision ? Neglect the size of the bobs and assume the collision to be elastic.

Text Solution

Verified by Experts

The correct Answer is:
bob A does not rise
In this elastic collision velocity of masses are exchaged.
So `v_(A) = 0 rArr A` does not rise
