Question 3 A skier starts at the top of a 37-meter high mountain. She pushes off, giving herself an initial speed of 2.2 m/s. The mountain is very icy and so can be treated as frictionless. The level ground below the mountain has a coefficient of kinetic friction 0.357. a) What is the speed of the skier when she reaches the bottom of the hill? b) Use the work-energy theorem to compute how far she travels on the rough, horizontal ground before coming to rest.
