A T-bar tow is required to pull 73 skiers up a 600 m slope inclined at 15° above horizontal at a speed of?

Question

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 85 kg.

Answer 1

First, compute the force of friction:

73*9.81*85*sin(15)*.06

Power=force*speed

P=2.5*73*9.81*85*sin(15)*.06
=2363 W

1 Horsepower = 0.7457 Kilowatts

=3.2 hp
