A ski tow is operated on a 20 degree slope of lenth 300m. The rope moves at 12.0km/h, and power is provided for 70 riders at one time with an average mass per rider of 65kg. Estimate the power required to operate the tow.

2. Relevant equations

P = Work / t

P = F * v

3. The attempt at a solution

60kg * 70 riders = 4550kg

Solving for time:

V = 12km/h = 3.33m/s

t = d / V

= 300m / 3.33m/s

= 90.09s

P = (F * d) / t

P = ((4550kg)(9.8m/s^2)( 300m))/(90.09s)

= 148484.8485 watts

I dont see what is the angle used for

maybe for another component of force? or is it no use?
