1. A T-bar tow is required to pull 89 skiers up a 600 m slope inclined at 15° above horizontal at a speed of 2.5 m/s. The coefficient of kinetic friction is 0.06. Find the motor power required if the mass of the average skier is 65 kg.




2. w=F*d
P=F*v




3. I found the normal force to be 615.923 N I then found the frictonal force to be 36.955N. Where do i go from here?

If you know the frictional force, how much work does it do on the skier? Are there any other forces doing work on the skier?
