a farmer hooks his tractor to a sledge loaded with firewood and drags it 20 m above the horizontal ground. The total weight of the sled and the load is 14,700 N. The tractor exerts a constant force of 5000 N at 370 on the horizontal, as indicated in the figure. A frictional force of 3,500 N opposes the movement of the sled. Calculate the total work done on the sled by all the forces involved.
