With what acceleration should a car moving at a speed of 36 km / h brake to stop after 10 seconds?

We calculate the acceleration of the car using the formula:
a = (V – V0) / t, where a is the acceleration of the car, V is the final speed of the car (V = 0 m / s), V0 is the initial speed of the car (V0 = 36 km / h = 36 * 1000/3600 = 10 m / s), t is the braking time of the car (t = 10 s).
Let’s calculate the acceleration of the car:
a = (V – V0) / t = (0 – 10) / 10 = -1 m / s².
Answer: The car must brake with an acceleration of 1 m / s².
