The tractor-trailer unit is moving down the incline with a speed of 4.9 mi/hr when the driver brakes the tractor to a stop in a distance of 4.5 ft. Estimate the percent increase n in the hitch-force component which is parallel to the incline, compared with the force present at steady speed. The cart and its load combined weigh 540 lb. State any assumptions.
