You have to specify the power output of a motor for a ski tow rope that will carry 20 skiers at a time. The grade of the ski slope is 32∘∘ above horizontal, and the average coefficient of kinetic friction between skis and snow is 0.12. The tow speed is to be 3.0 m/sm/s and each skier has an inertia of 60 kgkg (a reasonable average value) What must the minimum power output of the motor be?
