A skier with a mass of 75kg starts from rest at the top of a slope which is 110m tall and skis to the bottom. Hint: you must use conservation of energy to solve both parts of this problem. a. What is the skier’s speed at the bottom of the slope if there is no friction? b. If the speed of the skier at the bottom of the slope is actually 20m/s, how much work is done by friction?

A skier of mass 75kg starts from rest at the top of a friction less incline that is 20.0 m in height. As soon as she touches the bottom of the incline, she encounters a horizontal surface that is 1000 m long and the skier eventually comes to rest. The coefficient of kinetic friction between skier and snow is 0.205. Find the distance the skier covers before coming to rest. Show all work.

A skier starts from rest at the top of a hill that is inclined at 10.8° with respect to the horizontal. The hillside is 245 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest?
