A 70 kg man is initially at rest in a stationary 45 kg boat. The man steps out of the boat and onto the dock. If he moves out of the boat with a speed of 2.5 m/s to the right, what is the final velocity of the boat? (The total momentum of the man and the boat before and after the man steps out of the boat is equal.)

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
