Asked by Sarah
a 61 kg skier on level snow coasts 184 m to stop from a speed on 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 skis and the snow.

Original KE=work done by friction
1/2 m v^2=mu*mg*distance
solve for mu. Notice mass of the skier has nothing to do with it.
