A 60.4 kg skier coasts up a sho ered hill that makes an angle of 24.0 with the horizontal. The initial speed of the skier is 8.22 m/s. After coasting a distance of 2.00 m up the slope, the speed of the skier is 3.21 m/s. (a) Find the work done by the kinetic frictional force that acts on the skis. (b) What is the magnitude of the kinetic frictional force?
