How long does it take to accelerate a car, if it has increased its speed from 15 km / h to 30 km / h, moves with an acceleration of 0.5 km / h.

As we know from the school physics curriculum, in order to determine the time, if the body moves uniformly, it is possible to use this formula:

t = (v – v0): a, where v is the final velocity, v0 is the initial velocity, and is the acceleration.

Let’s determine how much time it took for the car to accelerate from 30 km / h to 15 km / h, when their conditions of our assignment we know that its acceleration was 0.5 km / h2:

(30 – 15): 0.5 = 15: 0.5 = 30.

Answer: 30 hours.
