A 60.0 kg skier starts from rest at the top of a ski slope 65.0 m high. Now moving horizontally, the skier crosses a patch of soft snow where u = 0.23. If the patch is 82.0 m wide and the average force of air resistance on the skier is 160 N, how fast is she going after crossing the patch? Express your answer in meters per second to three significant figures. Vo AEd m/s • Part C The skier hits a snowdrift and penetrates 3.0 m into it before coming to a stop. What is the magnitude of the average force exerted on her by snowdrift as it stops her? Express your answer in newtons to three significant figures. να ΑΣΦ F = N
