What is the acceleration of the train when approaching the station if it stops in a time equal to 50 s? The initial speed of the train is 90 km / h
These problems: t (the time it took for the train under consideration to stop) = 50 s; V0 (initial speed) = 90 km / h (SI V0 = 25 m / s).
The acceleration of the train under consideration when approaching the station is calculated by the formula: a = (V – V0) / t.
Calculation: a = (0 – 25) / 50 = -0.5 m / s2.
Answer: When approaching the station, the train in question had an acceleration of -0.5 m / s2.
