Question

Workhorses on Erie Canal How much work W is done by each horse in a time t? Express the work in terms of the quantities given in the problem introduction Constants Two workhorses tow a barge along a straight canal. Each horse exerts a constant force of magnitude F, and the tow ropes make an angle with the direction of motion of the horses and the barge. (Figure 1)Each horse is traveling at a constant speed v View Available Hint(s) Submit Figure of 1 Incorrect; Try Again; 5 attempts remaining The horses apply a nonzero force in the direction of a nonzero distance. Therefore, they do work. Part B How much power P does each horse provide? Express your answer in terms of the quantities given in the problem introduction. View Available Hint(s)

Explanation / Answer

(A) P = F.v

P = F v cos(theta)

Work done = Power x time

W = F v t cos(theta)

(B) P = F v (cos(theta))
