A 62.0kg skier on level snow coasts 164m to a stop from a speed of 1.40m/s.
A. Use the work-energy principle to find the coefficient of kinetic friction between the skis and the snow.
B. Suppose a 73.0kg skier with twice the starting speed coasted the same distance before stopping. Find the coefficient of kinetic friction between that skier's skis and the snow.
