A roller coaster car sits on a peak. Just before it moves down the track, the
car's potential energy is 10,000 joules. Halfway down the hill, its potential
energy decreases to 4,000 joules. What is the work done by the car to reach
this point? Assume that the track has negligible friction.
14,000 joules
10,000 joules
