Problem:
You are playing a pool and decide to practice your ability to make trick shots. In this trick shot you are attempting to strike an object ball (one of the pool balls with numbers on them) with the cue ball (the white ball that you strike with the cue stick) while the object ball is moving (usually the object ball is sitting still) and make the shot. If the object ball is moving directly from you at a speed of 0.10 m/s and you strike the cue ball at 0.50 m/s directly in-line with the object ball, then after the cue ball and object ball collide, how fast will they be moving apart relative to one another? Please give your answer in units of m/s, however, do not explicitly include units when typing your answer into the answer box. Including actual units will result in your answer being incorrectly scored.
