The car traveled a distance of 30m, with what acceleration it was moving if its speed at the initial moment

The car traveled a distance of 30m, with what acceleration it was moving if its speed at the initial moment of time was 14.4 km / h, and at the end of the path was 10m / s.

Task data: S (distance traveled) = 30 m; V1 (speed of a given vehicle at the initial moment of time) = 14.4 km / h (in SI V1 = 4 m / s); V2 (speed at the end of the path) = 10 m / s.
To determine the acceleration with which a given car was moving, we use the formula: S = (V2 ^ 2 – V1 ^ 2) / 2a, whence a = (V2 ^ 2 – V1 ^ 2) / 2S.
Let’s perform the calculation: a = (10 ^ 2 – 4 ^ 2) / (2 * 30) = 84/60 = 1.4 m / s2.
Answer: The given car was moving with an acceleration of 1.4 m / s2.
