Aski tow operates on a slope of angle 15.6 ∘ of length 340 m . the rope moves at a speed of 12.7 km/h and provides power for 53 riders at one time, with an average mass per rider of 69.0 kg .
estimate the power required to operate the tow

The power required to operate the tow is 34020.45 W.

The weight of a single rider is calculated as follows;

W = 53 x 181.84

W = 9637.52 N

The power required to operate the tow is calculated as follows;

P = Fv

where;

P = 9637.52 x 3.53 = 34020.45 W

P = 34034.2 Watt

Explanation:

As we know that the slope angle is given as

now the weight of the rider along the slope is given as

now total weight of all 53 riders along the slope is given as

now the speed of the rope is given as

now the power required is given as
