A train consists of a 50-Mg engine

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 40 , 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.
Also, determine F acting on the engine wheels.
