Cue balls on coin operated billiard tables are either larger than the numbered balls or are magnetic. This allows them to be returned for play in the event they are accidentally pocketed (i.e., scratched). 4. A 0.17 kg cue ball is moving at 4.0 m/s when it strikes a 0.16 kg stationary numbered ball (object ball). After the collision, the cue ball moves 60 to the left of its original direction while the object ball moves 30 to the right of the cue ball's original path.
