Two snowy peaks are at heights H and h above the valley between them. A ski run extends between the peaks at an average slope of 0. a) A skier starts from rest at the top of the higher peak. At what speed will he arrive at the top of the lower peak if he coasts without using ski poles? Ignore friction. Н ө ө b) What coefficient of friction between the snow and skis would make him stop just at the top of the lower peak?
