A farmer hitches her tractor to a sled loaded with firewood and pulls it a distance of 20 m along level ground. The total weight of sled and load is 14,700 N. The tractor exerts a constant 5000-N force at an angle of f = 36.9° above the horizontal, as shown in the figure. A 3500-N friction force opposes the sled’s motion.
