Question A Skier with a mass of 65.0 kg. Including equipment, starts from rest and accelerates down a slope. The slope is 27.0 m higher at the top than the bottom. The work done on the skier by the kinetic friction is 1.20 x 10^4 J. How would I determine the Gravitational potential energy at the top slope relative too the bottom? Kinetic energy at the bottom? And the skiers speed at the bottom of the slope?
