In a game of billiards a player wishes to sink a target ball in a corner pocket. If the angle to the corner pocket is 35 degrees, at what angle is the cue ball deflected. Assume that friction and rotational motion are unimportant and that the collision is elastic. Also assume that billiard balls have the same mass.
