Consider a wall and a ball that is traveling towards the wall with uniform velocity. Assuming no friction of any kind in this situation. When ball collides with the ball, the ball gets squished as its kinetic energy is changed to elastic potential energy and bounces back with Potential energy changing back to kinetic energy.
Now, suppose at the instant when ball is in contact with the ball and its potential energy is maximum the wall disappears. Then what will be the ball's behavior (or motion)?
I think that the ball will start oscillating- expand and contract horizontally repeatedly; with no more translation motion. Am I thinking in right direction?
