A skier starts from rest at the top of a hill that is inclined at 10.5 degree with the horizontal. The hillside is 191 meter long, and the coefficient of friction between snow and skis is 0.0677. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged.
Determine how far does the skier move along the horizontal portion of the snow before coming to rest?
