A T-bar tow is planned in a new ski area. At any one time, itwillbe required, to pull a maximum of 76skiers up a 591-m slopeinclined 15°at above the horizontal at a speed of 2.50 m/s. Thecoefficient ofkinetic friction between the skiers skis and the snowis typically0.059. As the manager of the facility,what motor powershould you request of the construction contractorif the mass of theaverage skier is 71.0kg. Assume you want to be ready for anyemergency and will order amotor whose power rating is 50 percentlarger than the bareminimum.
