Answer:

- 0.25m/s²

Explanation:

Given parameters:

Initial velocity  = 40m/s

Final velocity  = 30m/s

Time taken  = 40s

Unknown:

Acceleration of the car  = ?

Solution:

Acceleration is the rate of change of velocity with time.

 So;

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

 Acceleration  = [tex]\frac{30 - 40}{40}[/tex]    =  - 0.25m/s²

This implies that the car will decelerate at a rate of 0.25m/s²
