A cart for hauling ore out of a gold mine has a mass of 445 kg, including its load. The cart runs along a straight Track stretch of track that climbs a shallow 4.87" incline. A donkey, .--.Rope which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 455 N force for a distance of 173 m by means of a rope that is parallel to the slope but makes an angle of 12.9* with the track. Track incline Horizontal ground Model the rolling resistance of the cart as though it were sliding on the track with a coefficient of friction of 0.0167. Use g = 9.81 m/s , and note that angle A in the image is the angle of the incline while angle B is the angle the rope makes with the track. Find the work Wa that the donkey performs on the cart during this process. WA = Find the work W. that the force of gravity performs on the cart during this process.Find the work Wa that the donkey performs on the cart during this process. Wa = Find the work W. that the force of gravity performs on the cart during this process. WE Calculate the work Wr done on the cart by friction during this process. W/ =
