Question

1 An electric train is initially at rest at a railway station. The motor causes a constant force of 360 000 N
to act on the train and the train begins to move.
The train travels a distance of 4.0 km along a straight, horizontal track.
(a) Calculate the work done on the train during this part of the journey.

Answer 1

Answer:

Answer 2

Answer: 14,40,000 J

Explanation:

Work = Force * distance

Force = 360000 N

Displacement = 4.0 km

Work = 360,000 N * 4.0 Km

         = 14,40,000 NKm or Joule
