A T-bar tow is planned in a new ski area. At any one time, itwillbe required to pull a maximum of 80 skiers up a 600 m slopeinclinedat 15 degrees above the horizontal at a speed of 2.5m/s. Thecoefficient of kinetic friction between the skiersskis and the snowis typically 0.060. As the manager of thefacility, what motor powershould you request of the constructioncontractor if the mass of theaverage skier is 75.0 kg. Assuming you want to be ready for anyemergency and will order amotor whos power rating is 50% largerthan the bareminimum.
