The train, leaving the station, picks up speed 15 m / s in 150 s. What is its acceleration?

To determine the acceleration with which the train gained speed equal to 15 m / s, we apply the formula: a = (V – V0) / t, where V is the gained speed (V = 15 m / s); V0 – initial speed (V0 = 0 m / s, the train departed from the station); t – time of speed gain (t = 150 s).
Let’s perform the calculation: a = (15 – 0) / 150 = 0.1 m / s2.
Answer: To gain a speed of 15 m / s, the train moved with an acceleration of 0.1 m / s2.
