=  
Where :
  •  is the average acceleration .
  •   is the displacement travelled .
  •   is the time the car took to stop .
  •   is the the time the car took to make this displacement with constant velocity .
  •  is the final average velocity of the car.
  •  is the initial average velocity car.
