A65.2-kg skier coasts up a snow-covered hill that makes an angle of 33.3 ° with the horizontal. the initial speed of the skier is 8.05 m/s. after coasting a distance of 1.26 m up the slope, the speed of the skier is 4.54 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?
