Question:
A skier with a mass of 80 kg starts from rest at the top of a ski slope 75.0 m high. Assuming negligible friction between the skis and the snow, how fast is she going at the bottom of the slope? Now moving horizontally, the skier crosses a patch of rough snow, where the coefficient of friction is 0.2. If the patch is 225 m wide, how fast is she going after crossing the patch? The skier hits a snow drift and penetrates 2.5 m into it before coming to a stop. What is the average force exerted on her by the snowdrift as it stops her?
