Acceleration is defined as the rate of change of velocity per unit of time. In this case, we can calculate it using the formula:

Acceleration = (Final velocity - Initial velocity) / Time

Here, the final velocity is 10 meters/second, the initial velocity is 20 meters/second, and the time is 5 seconds.

So, the acceleration is:

Acceleration = (10 m/s - 20 m/s) / 5 s = -10 m/s / 5 s = -2 m/s²

The negative sign indicates that the car is decelerating or slowing down. So, the acceleration of the car is -2 meters per second squared.
