An astronaut in orbit outside a capsule uses a re- volver to control motion. The astronaut with gear weighs 200 lb on earth. If the revolver fires 0.05-lb bullets at 2700 ft/s and ten shots are fired, what is the final velocity of the astronaut? Compare the final kinetic energy of the ten bul- lets with that of the astronaut. Why is the differ- ence so great?
