A 62.1 kilogram skier coasts up a snow-covered hill that creates an angle of 23.1 degree with the horizontal. The initial speed of the skier is 8.90 m/s. After coasting a distance of 2.07 meter up the slope, the speed of the skier is 3.35 m/s. Find the work done by the kinetic frictional force that acts on the skier.
