The train moves with an acceleration of 0.5 m / s by how much the train speed will change in 20 seconds.

These tasks: a (the acceleration with which the train under consideration is moving) = 0.5 m / s2; t (duration of accelerated movement) = 20 s.

The change in the speed of the train in question is determined by the formula: ΔV = a * t.

Let’s calculate: ΔV = 0.5 * 20 = 10 m / s.

Answer: The speed of the train in question will change by 10 m / s.
