…ball has a small velocity, or speed. Since momentum is a vector quantity, it describes both magnitude and direction. To truly conserve momentum, the direction of the balls resulting from the collision must also cancel out with the direction of the cue ball. The get a ball to go exactly where you want it, just calculate the angle desired, and strike the cue ball with the appropriate velocity. Who said physicists weren't up for sports?
