# The train in 10 seconds after the start of movement acquires a speed of 0.6 m / s.

The train in 10 seconds after the start of movement acquires a speed of 0.6 m / s. How long after the start of movement the speed of the train will become equal to 3 m / s?

To determine the acceleration time of a given train to a speed of 3 m / s, we use the equality: V1 / t1 = a (constant train acceleration) = V2 / t2, whence we express t2 = V2 * t1 / V1, where V2 is the required speed (V2 = 3 m / s); t1 – the first time of movement (t1 = 10 s); V1 – first speed (V1 = 0.6 m / s).

Let’s perform the calculation: t2 = 3 * 10 / 0.6 = 30 / 0.6 = 50 s.

Answer: The train will accelerate to a speed of 3 m / s in 50 seconds.
