A farmer hitches her tractor to a sled loaded with firewood and pulls it a distance of 20 m along level ground (Fig.). The total weight of sled and load is 14,700 N. The tractor exerts a constant 5000 N force at an angle 36.9° of above the horizontal. A 3500 N friction force opposes the sled's motion. Find the work done by each force acting on the sled and the total work done by all the forces. |(a) (b) Free-body diagram for sle =5000N 0= 36.9° 180 f=350ON S=20m w=14700N
