A farmer hitches her tractor to a sled loaded with firewood and pull it a distance of 20 m along the level ground. The total weight of sled and the load is 14700 N. The tractor exerts a constant 5000 N force at a n angle of 36.9 degrees. There is a 3500 N friction opposing the sled's motion. Find the work done by each force acting on the sled and the total work done by all forces in J (joules).
