A 100 tonne locomotive is coupled to a 200 tonne train by a draw bar. It pulls the train up a I in 200 incline at a constant velocity of 20 km/h against a tractive resistance of 50 N/tonne. During the asçent the drawbar fails. Calculate EACH of the following: The power developed by the locomotive prior to the drawbar failure; b The minimum gap between the train and the locomotive 10 seconds after the drawbar failure.
