Acart for hauling ore out of a gold mine has a mass of 413 kg , including its load. the cart runs along a straight stretch of track that climbs a shallow 4.09° incline. a donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 366 n force for a distance of 163 m by means of a rope that is parallel to the slope but makes an angle of 14.7° with the track. the coefficient of friction for the cart\'s wheels on the track is 0.0105. take g = 9.81 m/s2. find the work that the donkey performs on the cart and gravity performs on the cart during this process. as well as calculate the work done on the cart during the process by friction.
(a)-donkey work on cart:
(b)-gravity work on cart:
(c)-friction work on cart:
