A 61.8 kg skier coasts up a snow-covered hill that makes an angle of 26.0° with the horizontal. The initial speed of the skier is 6.10 m/s. After coasting a distance of 1.86 m up the slope, the speed of the skier is 4.48 m/s. Calculate the work done by the kinetic frictional force that acts on the skis.

    intialKE-changePE-friction=finalKE

    for the change in PE, use the slope distance and sine of the angle to get change in height.
