The car acquires a speed of 54 km / h in 10 seconds. determine the acceleration of the vehicle.

Let’s designate the initial vehicle speed as 0 m / s.

We translate the speed that the car acquired in 10 seconds from km / h to m / s.

Since in 1 km – 1000 meters, and in an hour – 3600 seconds, we get:

54 * 1000/3600 = 15 m / s.

Determine the difference between the final and initial speed.

15 – 0 = 15 m / s.

We find acceleration.

To do this, we divide the difference in speeds by the time during which it acquired this speed, namely 10 seconds.

We get:

15/10 = 1.5 m / s2

Answer:

Vehicle acceleration was 1.5 m / s2
