Consider a train consisting of an engine of mass 55 tonne pulling 10 trucks, each of mass 13 tonne, travelling up an incline of 1 in 100 (sine). The rolling resistance to motion is 40 N/tonne, and the train's speed is increased from 20 km/h to 37 km/h over a distance of 600 m. Enter all the following answers in the units shown. Calculate: (a) the total mass of the train: kg. (b) the change in height of the train: metres. (c) the change in potential energy of the train: MJ. (d) the starting velocity of the train: m/s. (e) the final velocity of the train: m/s. (f) the change in kinetic energy of the train: MJ. (g) the work done against the rolling resistance: MJ. (h) the total work done by the engine: MJ.
