A = Theta.
W = (F*cosA) * V*t.
P = (F*cosA) * V
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 θ with the direction of motion of the horses and the barge. (Figure 1) Each horse is traveling at a constant speed v.
How much work W is done by each horse in a time t?
