A 63 kg skier coasts up a snow-covered hill that makes an angle of 25 degrees with the horizontal. The initial speed of the skier is 6.6 m/s. After coasting a distance of 1.9 m up the slope, the speed of the skier is 4.4 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?
