A 61 kg skier on level snow coasts 184 m to a stop from a speed of 12.0 m/s.
a. Use the work-energy principle to find the coefficient of kinetic friction between the skis and the snow. b. Suppose a 75 kg skier with twice the starting speed coasted the same distance before stopping. Find the coefficient of kinetic friction between that skier's skisand the snow.
