HMCHOZWorkhorses on Erie Canal Workhorses on Erie Canal Part A Two workhorses tow a barge along a straight canal Each horse exerts a constant forco of magnitude F, and the tow ropes make an angle with the diroction of moon of the horses and the barge (Eiguro 1) Each horse is traveling at a constant speed How much work W is dono by oach horse in a time t? Express the work in terms of the quantitios given in the problem introduction. Submit Hints My Answers Give Lip Review Part Part B How much power P does each horse provide? Express your answer in torns of the quantities given in the problem introduction. Subenit P.Explanation / Answer
part A )
Here ,
force acting in the forward direction , Ft = 2*F * cos(theta)
Now,
work done by each horse = F*distance * cos(theta)
work done by each horse =F * cos(theta) * (speed * time)
work done by each horse =F * cos(theta) * (v*t)
the work done vy each horse is F*cos(theta)*v*t
part B)
Power by each horse = work done /time
Power by each horse = F*cos(theta)*v*t/(t)
Power by each horse = F*cos(theta)*v
the power of each horse is F*cos(theta)*v
