Given:
a = 3 m / s ^ 2 – vehicle acceleration;
V0 = 0 m / s – the speed of the car at the beginning of the journey (since, according to the conditions of the problem, it started off);
t = 4 s – movement time;
It is required to find V1 – the speed that it will acquire in time t.
a = (V1 – V0) / t, hence V1 = V0 + at = 0 + 3 * 4 = 12 m / s.
Answer: the car will acquire a speed of 12 m / s.
