A skier starts from rest at the top of a hill that is inclined at9.5°with the horizontal. The hillside is 150 m long, and the coefficient of frictionbetween snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How fardoes the skier glide along the horizontal portion of the snowbefore coming to rest?
