An 8000 kg engine pulls 40000 kg train alonged a level track and gives an acceleration of 1.2m/s2. Find the accelaration produced by same engine on a train of mass 16000kg?
Answer:
Force exerted by the engine = mass of train x acceleration = 40000 x 1.2=48000N
When the same engine pulls a 16000 kg train, the acceleration = 48000/16000=3m/s2
