A 63-kg skier (with gear) goes down a 500 meter slope which makes a 16 degree anglewith horizontal. They start with zero velocity.a. What is the gravitational potential energy the skier begins with? (500 meters isnot the height)b. If there is no friction or air resistance, what would their velocity be when theyreach the bottom of the hill?C. If friction and drag together remove energy from the skier by applying 50 N offorce during the entire trip, how much energy is removed?d. In this case with friction/drag in part c, what would the skier's velocity be whenthey reach the bottom of the hill?
