There is a rectangular surface with no friction, and a puck with no friction on its bottom surface sits at a random point on this surface. This puck is now given a push in a random direction. The walls of the surface all have coefficient of restitution of 1, so the puck will bounce off the walls forever at the same speed.(adsbygoogle = window.adsbygoogle || []).push({});

What is the probability that the puck will eventually pass through the same point, moving in the same direction ?
