A freight train consists of two kg 1000.8 4 − × engines and 45 cars with average masses of kg 1050.5 4 × . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 2 –2 m/s 10.005 × if the force of friction is N 1050.7 5× , assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains...
