With what acceleration does the car move if it increases its speed from 12m / s to 20m / s in 20s.

Acceleration is found by the formula a = (v2-v1) / t
where a is the acceleration, v2 is the final speed, v1 is the initial speed, t is the travel time. Therefore, substituting the known values into this formula, we get: (20m / s – 12m / s) / 20s = (8/20) and / s ^ 2 = 0.4 m / s ^ 2
(meter / second squared – unit of acceleration in SI)
Answer: 0.4
