... 8. How much work will be done by a 30-gram bullet that is traveling at 200 m/s? From energy conservation, the amount of work the bullet can do is at most equal to its kinetic energy. So the most work the bullet can do is 600 Joules. 9. A force of 50 pounds is used to push a box 10.0 ft across a leve ...

... that the work that goes into a system becomes the kinetic energy of that system. For example, if I do 150 J of work lifting a bowling ball to the top of a hill, and then released it from rest to roll down the hill, the kinetic energy of the bowling ball would be 150 J at the bottom of the hill. ...
