Coefficient of friction between skis and snow

Reference no: EM13671691

A 78 kg cross-country skier glides over snow as in the figure below. The coefficient of friction between skis and snow is 0.50. Suppose all the snow beneath his skis is at 0°C and that all the internal energy generated with friction is added to snow, which sticks to his skis until it melts. How far would he have to ski to melt 1.0 kg of snow?
