Answer:

The acceleration of the car is  -5m/s²

Explanation:

Given parameters:

Initial velocity  = 75m/s

Final velocity  = 0m/s

Time  = 15s

Unknown:

Acceleration of the car = ?

Solution:

Acceleration is the rate of change of velocity with time;

Mathematically;

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

Insert parameters and solve,

   Acceleration  = [tex]\frac{ 0- 75}{15}[/tex]   = -5m/s²

The acceleration of the car is  -5m/s²
