A skier with a mass of 75kg starts from rest at the top of aslope which is 110m tall and skis to the bottom. Hint: you must useconservation of energy to solve both parts of this problem. a. Whatis the skier’s speed at the bottom of the slope if there is nofriction? b. If the speed of the skier at the bottom of the slopeis actually 20m/s, how much work is done by friction?
