How long does it take for a car, moving with an acceleration of 0.5 m / s2, to increase its speed from 15 to 25 m / s?

As we know from the school physics curriculum, in order to determine the time of movement with uniformly accelerated movement, it is possible to use the following formula:

t = (v – v0) / a, where v is the final speed, v0 is, respectively, the initial speed, a is the acceleration with which the body moves.

Let us determine what value will be equal to the time during which the specified car will increase its speed from 15 m / s to 25 m / s, if its acceleration is 0.5 m / s2:

(25 – 15): 0.5 = 20.

Answer: Time = 20 s.
