Homework Help: Average coefficient of friction

  1. Oct 15, 2008 #1
    1. The problem statement, all variables and given/known data
    A skier traveling 11 m/s reaches the foot of a steady upward 22° incline and glides 13 m up along this slope before coming to rest. What was the average coefficient of friction?

    2. Relevant equations

    3. The attempt at a solution
    Can someone help me get started by helping me with the equation and figuring out how mass cancels out?
