A locomotive of mass 24 000 24\,000\,24000 kg is coupled to a passenger coach of mass 16 000 16\,000\,16000 kg. The train accelerates at 0.50 m s-2 along a level straight track. Resistive forces of 1800 N and 1200 N act on the locomotive and coach respectively. The coupling is light and horizontal.
Find the tension in the coupling.
Find the driving force produced by the locomotive.
