(II) A 75-kg skier grips a moving rope that is powered by an engine and is pulled at constant speed to the top of a 23° hill. The skier is pulled a distance x = incline and it takes 2.0 min to reach the top of the hill. If the coefficient of kinetic friction between the snow and skis is uk = 0.10, what horsepower engine is required if 30 such skiers (max) are on the rope at one time? 220 m along the %3D

Expert Solution
Given

Given:

Mass,m=75kgAngle,θ=230Distance,x=220mCoefficient of kinetic friction,μk=0.10Time,t=2min=120s

The quantity of energy moved or transformed per unit time is referred to as power. The watt, which is equal to one joule per second in the International System of Units, is the unit of power. Power is also referred to as activity in older works. A scalar quantity is a power.

Horsepower is a unit of measurement for power, or the rate at which work is completed, generally in relation to the engine or motor output. There are a variety of horsepower specifications and kinds.
