A 52 kg skier is at the top of a slope, as in the

figure. At the initial point A, the skier is 17.7

m vertically above the final point B.

The acceleration of gravity is 9.81 m/s2 .

Find the difference in gravitational po-

tential energy associated with the skier at the

points A and B if the zero level for gravita-

tional potential energy is at point B.

Answer in units of J.
