PROBLEM-10 GRAVITATIONAL POTINTIAL ENERGY In a typical professional downhill ski race, athletes start 820 m above where they cross the finish line. Assume that they start at rest, friction is negligible, and their mass is 80 kg. What is the magnitude of the change in gravitational potential energy of the Earth-athlete system over the course of the race? (in J )
