Atrain consists of a 60 mg engine and three cars, each having a mass of 25 mg . if it takes 90 s for the train to increase its speed uniformly to 45 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. also, determine f, acting on the engine wheels
