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 slowing down at 20 km/h (b) the force in the coupling between the cars at car B while the train is slowing down. 90 km/h 25 Mg 20 Mg
