A 75 kilogram skier grips a moving rope that is powered by an engine and is pulled at constant speed to the top of a 23 degree hill. The skier is pulled to a distance x = 220 meter along the incline and it takes 2.0 minute to reach the top of the hill. If the coefficient of kinetic friction between the skies and the snow is uk =0.10, obtain what is the horsepower of the engine required if 30 such skiers (max) are on the rope at one time?
