A skier of mass 70.0 kg rides a ski lift to the top, which is 500 m higher than the base of the lift. (a) Find the increase in the skier’s gravitational potential energy. (b) Find the minimum work done by the force exerted on the skier by the lift. (c) When the skier skis down the run, what would her final velocity be if no force other than gravity did work? What other forces do work?
