A locomotive draws a train of mass 400 tones, including its own mass, on a level ground with a uniform acceleration, until it acquires a velocity of 54km/h in 5 minutes. if the frictional resistance is 40N per tone of the mass and the air resistance varies with the square of the velocity, find the power of the engine. Take the air resistance as 500Nat 18km/h.
