The car moving uniformly accelerated, 10 seconds after the start of movement reached a speed of 54 km

The car moving uniformly accelerated, 10 seconds after the start of movement reached a speed of 54 km / h Find the acceleration of the car.

Vehicle speed can be set by the formula:

V = V0 + a * t, where V is the vehicle speed at time t (V = 54 km / h = 54 * 1000/3600 m / s = 54 / 3.6 m / s = 15 m / s), V0 Is the initial speed of the car (we assume that the car started moving with V0 = 0 m / s), a is the required acceleration of the car, t is the time of movement (t = 10 s).

V = 0 + a * t and a = V / t.

Let’s perform the calculation:

a = V / t = 15/10 = 1.5 m / s2.

Answer: The acceleration of the car was 1.5 m / s2.
