Question

A skier starts from rest at the top of a hill that is inclined at 9.8° with the horizontal. The hillside is 170 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?

Answer 1

during the slide down the hill:
use a=gSin9.8-mu*gCos9.8 to find vel. at the base of the incline. For the horizontal part accleration is -mu*g - to find the distance covered.
Figure it out based on the above hint
