The speed of the train increases from 15 m / s to 20 m / s. Find the acceleration path of the train if its acceleration is 0.5 m / s.
Problem data: V0 (initial speed of the train under consideration) = 15 m / s; V (train speed after acceleration) = 20 m / s; a (acceleration) = 0.5 m / s2.
The acceleration path of the train under consideration is determined by the formula: S = (V ^ 2 – V0 ^ 2) / 2a.
Calculation: S = (20 ^ 2 – 15 ^ 2) / (2 * 0.5) = 175 m.
Answer: The acceleration path of the train in question was 175 meters.
