Q:
I'm curious to know whether or not we use momentum while hitting the ball on wall in Squash for a powerful shot. What's the physics behind it?

A:

For a powerful shot, you must move the racquet faster.  A fast moving racquet has both more momentum and energy than a slow one, and the speed of the ball after the collision depends on both.  The final speed also depends on how fast the ball is approaching the racquet before the collision.  The answer depends on the momentum and energy of each object.
