A body of mass m is released from a height h on a smooth inclined plane that is shown in the figure. The following can be true about the velocity of the block knowing that the wedge is fixed. .

A

`v` is highest when it just touches the spring

B

`v` is highest when it compresses the spring by some amount

C

`v` is highest when the spring comes back to natural position

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity is maximum when acceleration is zero. It means net force is zero. Net force is zero after some compression.
