We have:
Initial velocity (u) = 32 m/s
Final velocity (v) = 0 m/s ⇒ The value is zero because the car comes to stationary position when it stops
Time = 14 seconds
We can use one of the constant acceleration equation:
where 
is the acceleration
The acceleration is 2.3 m/s⁻² and the negative sign shows deceleration
