Part A A train consists of a 55 Mg engine and three cars, each having a mass of 35 Mg. If it takes 75 s for the train to increase its speed uniformly to 39 km/h, starting from rest, determine the force T, developed at the coupling between the engine E and the first car A. The wheels of the engine provide a resultant frictional tractive force F which gives the train forward motion, whereas the car wheels roll freely. Express your answer with the appropriate units.
