A 2000 kg tractor, starts at the bottom of a 50. m mountain while traveling at 45 m/s. During the trip, air resistance does -100 kJ of work on the tractor, and friction does an additional -550 kJ of the work. What is the minimum amount of work the engine must do in order for the tractor to reach the top?
