A locomotive is pulling 9 freight cars, each of which is loaded with the same weight. The mass of each loaded car is 37,000 kg, and we can neglect friction on these 9 cars. If the train is accelerating forward at 0.81 m/s²2² on a level track, what is the tension in the coupling between the second and third cars? (The car nearest the locomotive is counted as the first car.)
