Homework Statement
A skier starts from rest at the top of a hill that is inclined at 9.1° with the horizontal. The hillside is 250 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?
The Attempt at a Solution
250sin9.1= 39.5 (height of hill)
v2 = 2gh
v2 = 2 (9.8 m/s2)(39.5m)
v= 27.8 m/s
d= v2 / 2 u g
d= 27.8 m/s / 2 (0.0750) (9.8 m/s2)
d= 18.9 m
