If the frictional resistance at any velocity is 45 N/ton, and if the change in speed is accomplished in a length of 100 m, a is work done on a level track in bringing the velocity of a train weighing 200 metric tons from zero to 48 km/hr If the track were a 1% upgrade, what would be the additional work to be done? In kN-m
