A 63.0 kg skier approaches the foot of a hill with a speed of 15.0 m/s. The surface of this hill slopes up at 50.0 degrees above the horizontal and has coefficients of static and kinetic friction of 0.750 and 0.250, respectively, with the skis. 1) Use energy conservation to find the maximum height above the foot of the hill that the skier will reach. Express your answer in meters.   2) Will the skier remain at rest once she stops, or will she begin to slide down the hill?
