In a game of ping-pong, suppose a paddle moves at 20 miles per hour and hits a ball with 20 mph in the opposite direction. ... In the new problem, a ball moving at -40 mph hits a non-moving surface; if the collision is elastic (no energy lost), that ball returns with the same speed but in the opposite direction, i.e. its velocity reverses sign. ... Something very similar happens when a spacecraft with velocity v passes close to a moving planet and is deflected. ...
