1. The problem statement, all variables and given/known data
A skier starts from rest at the top of a hill that is inclined at 10.5degrees with the horizontal. The hillside is 200 m long, and the coefficient of friction between the skis is 0.075. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier move along the horizontal portion of the snow before coming to rest? 2. Relevant equations F_{f}=μF_{norm} F_{net}=ma cosθ=adj/hyp sinθ=opp/adj tanθ=opp/adj 3. The attempt at a solution μ = .075 d = 200m incline = 10.5° I know I must use components to solve, but the way this problem is set up (lack of givens) I am having trouble solving it. Also I do not know how to calculate it once he hits horizontal land and is no longer on the slope. A walkthrough of this would be absolutely AMAZING! :)

Its a very very easy question!
All data required is given. You just need one equation to solve it. Think more about it.
