The hydraulic braking system for the truck and trailer is set to produce equal braking forces for the two units. If the brakes are applied uniformly for 10 seconds to bring the rig to a stop from a speed of 25 mi/hr down the 11-percent grade, determine the magnitude of the force P in the coupling between the trailer and the truck. The truck weighs 26,000 lb and the trailer weighs 20,000 lb.
