A two-car light rail travels at 45 mi / h. The weight of car A is 18 tons and that of car B is 13 tons. When the brakes are suddenly applied, the a constant 4,300-lb braking force on each car. Determine a) the time required for the train to stop after the brakes are applied, b) the force on the coupling between the wagons while the train is decelerating. Consider 1 ton = 907.2 kg.
