Acar traveling at 32 m/s starts to decelerate steadily. it comes to a complete stop in 14 seconds. what is its acceleration?

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

The first option would be correct if it were one half and not one
