12.11 The coefficients of friction between the load and the flatbed trailer
shown are = 0.40 and μ = 0.30. Knowing that the speed of the
rig is 72 km/h, determine the shortest distance in which the rig ca
be brought to a stop if the load is not to shift.

12.12 A light train made up of two cars is traveling at 90 km/h when the
brakes are applied to both cars. Knowing that car A has a mass of
25 Mg and car B a mass of 20 Mg, and that the braking force is
30 kN on each car, determine (a) the distance traveled by the train
before it comes to a stop, (b) the force in the coupling between the
cars while the train is slowing down.
