The train weighing 1500 tons increased its speed from 5 to 10 m / s for 150 s.

The train weighing 1500 tons increased its speed from 5 to 10 m / s for 150 s. Determine the force imparting acceleration to the train.

Let us determine the acceleration of the train, assuming that it was moving uniformly:
a = (10 – 5) / 150 = 1/30 m / s ^ 2.
The force acting on a body is equal to the product of the acceleration of the given body by its mass:
1,500,000 * 1/30 = 50,000 N = 50 kN.
