1. The problem statement, all variables and given/known data 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?
