A 73.0-kg skier starts from rest and slides down a 34.0-m frictionless slope that is inclined at an angle of 15.0° with the horizontal. Ignore air resistance.

If the slope is not frictionless so that the skier has a final velocity of 6 m/s, calculate the force of friction (assuming it is constant), and the coefficient of kinetic friction.
