Answer:
(a) Net accelerating force = 40000- 5000 =35000 N
(b) Acceleration of the train = 35/18 = 1.9444 metres per second square
Explanation:
Net acceleration force is Total force engine exerts - Friction force it needs to overcome = 40000 -5000 = 35000 N
Acceleration of the train is Force net divided by the mass of the train along with its wagons => 35000/(8000 +5*2000) => 35000/18000
