Two snow-covered peaks are at elevations of 862 m and 741 m above the valley between them. A ski run extends from the top of the higher peak to the top of the lower one; see Fig.13-17. (a) A skier starts from rest on the higher peak. At what speed would he arrive at the lower peak if he coasts without using the poles? Assume icy conditions, so that there is no friction. (b) After a snowfall, a 54.4-kg skier making the same run also without using the poles only just makes it to the lower peak. By how much does the internal energy of her skis and the snow over which she traveled increase?
