Question:
A tractor-trailer rig with a 2000-kg tractor, a 4500-kg trailer, and a 3600-kg trailer is traveling on a level road at 90 km/h. The brakes on the rear trailer fail and the antiskid system of the tractor and front trailer provide the largest possible force which will not cause the wheels to slide. Knowing that the coefficient of static friction is 0.75, determine
(a) The shortest time for the rig to a come to a stop,
(b) The force in the coupling between the two trailers during that time. Assume that the force exerted by the coupling on each of the two trailers is horizontal.
