Reference no: EM13531116

A subway train is traveling at a speed of 45 miles/hour whenthe brakes are fully applied on the wheels of cars A and B, causing them to slide on the track, but are not applied on the wheels ofcar C. Knowing that the coefficient of kinetic friction is .30between the wheels and the track, determine (a)the distancerequired to bring the train to a stop, (b)the time required tobring the train to a stop and (c) the force in each coupling. ** Car A=30tons Car B=40tons Car C=30 tons
