Four motors drive a 150 tonne motor coach which is each motor developing a torque of 6000 Nm during acceleration. If up-gradient is 45 in 1000, gear ratio a = 0.35, gear transmission efficiency 95%, wheel radius 0.6 m, train resistance 30 N/tonne, effective mass on account of rotational inertia is 10% higher, determine the time taken to attain a speed of 80 kmph.
