A train consists of a 50 Mg engine and three cars, each having a mass of 30 Mg. If it takes 80 s for the train to increase its speed uniformly to 43 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 friction tractive force F which gives the train forward motion, whereas the car wheels roll freely. Also, determine...
