Homework Help: Finding the coefficient of kinetic friction

  1. Oct 10, 2007 #1
    1. The problem statement, all variables and given/known data
    A 16.5 kg sled is being pulled across a horizontal surface at a constant velocity. The pulling force has a magnitude of 82.0 N and is directed at an angle of 30.0° above the horizontal. Determine the coefficient of kinetic friction.

    2. Relevant equations

    3. The attempt at a solution
    I have no idea where to begin.
