10. A poolio-coolio claims that he has perfected the greatest trick shot of all time. He claims that he can arrange three pool balls in the center of the table such that when he hits them with the cue ball some extraspecialness happens. He claims that the cue ball comes to rest, two of the balls move directly away from each other along a line perpendicular to the direction of the incoming cue ball, and the remaining ball moves in the direction of the cue balls original path. All of the balls involved have the same mass. Using your cunning physics prowess, prove that he is full of hot air. Hint: You will need to use momentum and kinetic energy.
