The question as text
A railway engine of mass 120000kg is towing a coach of mass 60000kg up a straight track inclined at an angle of ! to the horizontal where sin ! = 0.02. There is a light rigid coupling, parallel to the track, connecting the engine and coach. The driving force produced by the engine is 125000N and there are constant resistances to motion of 22000N on the engine and 13000N on the coach.
