Question
what is the solution to this problem? A 82 kg cross-country skierglides over snow as in Figure P11.25. The coefficient of frictionbetween skis and snow is 0.40. Assumeall the snow beneath his skis is at 0°C and that all theinternal energy generated by friction is added to snow, whichsticks to his skis until melted. How far would he have to ski tomelt 4.0 kg of snow?m what is the solution to this problem? A 82 kg cross-country skierglides over snow as in Figure P11.25.
