How fast does a racing car accelerate if its speed increases from 36 km / h to 72 km / h in 15 seconds?

The acceleration of a car at uniformly accelerated movement can be calculated by the formula:
a = (V – V0) / t, where V is the final speed of the vehicle (V = 72 km / h = 72 * 1000/3600 = 20 m / s), V0 is the initial speed of the vehicle (V0 = 36 km / h = 36 * 1000/3600 = 10 m / s), t is the time of vehicle movement (t = 15 s).
Let’s calculate the acceleration of the car:
a = (V – V0) / t = (20 – 10) / 15 = 0.67 m / s ^ 2.
Answer: Vehicle acceleration is 0.67 m / s ^ 2.
