13) A short commutator train consists of a locomotive and two cars. The mass of the locomotive is 6000kg and that of each car is 2000kg. The train pulls away from a station with an acceleration of 0.5ms -2. Determine the horizontal pulling force that the locomotive wheels exert on the track, the tension between the couplings joining the two cars and the tension between the couplings joining the two cars.
