What is tension in coupling among the second and third cars

Reference no: EM13668903

A locomotive is pulling 12 freight cars, each of which is loaded with roughly the same weight. The mass of each can be taken to be 37,000 kg. If the train is accelerating at 0.73m/s^2 on a level track, what is the tension in the coupling among the second and third cars? The car nearest the locomotive is counted as the first.
