Answer:

-5m/s²

Explanation:

Given parameters:

Initial velocity  = 25m/s

Time  = 5s

Final velocity  = 0m/s

Unknown:

Acceleration of the car  = ?

Solution

The acceleration of a body is the rate of change of the velocity of the body with time.

 Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time}[/tex]  

So;

 Acceleration  = [tex]\frac{0 - 25}{5}[/tex]    = -5m/s²

The car is decelerating at a rate of  5m/s²
