The cart runs along a straight stretch of track that is sloped 4.35 from the horizontal. A donkey, trudging along and to the side of track, job the by means cart up slope with a 418-N force for a distance of 119 m of a rope that is parallel to the ground and makes an of 14.7 with the The of for carts n the track is 0177. Use g 981 mis Find the work that the donkey performs on the cart during this process 14.7 Find the work that the force of gravity performs on the cart during the process. 35 Calculate the work done on the cart during the process by friction. horizontal ground O Previous 2 Check Answer Next ExtExplanation / Answer
donkey's work
W = F*d*costheta
W = 418 * 119 * cos4.35
W = 49598.7 J
part b )
work done by gravity
W = mg*dsintheta
W = 441 * 9.81 * 119 * sin4.35
W = 39048.457 J
part c )
Wf = mu*m*g*d*costheta
Wf = 9086 J
