A billiard ball is rolling across a pool table towards the front of a train at 2.2m/s while the train is moving forward at 6.3m/s.  How fast is the ball moving relative to the ground? Later the ball is rolling toward the back of the train at the same speed. What is the ball's velocity relative to the ground now?
