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 that 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.

A block of mass 20 kg is released from rest at the top of a ramp as shown in Figure 4. Thecoeficient of kinetic friction between block and ramp is μk = 0.25.

Three packages each of weight m = 9 kg A, B, and C are placed on a conveyor belt that is at rest. Between the belt and both packages A and C, the coefficients of friction are Ms = 0.30 and Mk = 0.20; between package B and the belt, the coefficients are Ms = 0.10 and Mk = 0.08.
