An electric freight train is initially at rest at a terminal. The train’s motor produces a constant force of 180 000 N180\,000\text{ N}180000 N to act on the train, and the train begins to move.
State the form of energy gained by the train as it begins to move.
The train travels a distance of 2.0 km2.0\text{ km}2.0 km along a straight, horizontal track.
Calculate the work done on the train during this part of the journey.
The mass of the train is 200 000 kg200\,000\text{ kg}200000 kg. Calculate the maximum possible speed of the train at the end of the first 2.0 km2.0\text{ km}2.0 km of the journey.
In practice, the speed of the train is much less than the value calculated in (b)(ii). Suggest one reason why this is the case.
After travelling 2.0 km2.0\text{ km}2.0 km, the train reaches its maximum speed. It continues at this constant speed on the next section of the track where the track follows a curve which is part of a horizontal circle. State the direction of the resultant force on the train as it follows the curved path.
