Arace car is moving with a velocity of 144 kilometers/hour. the driver applies the brakes, and the car comes to a halt in 12.0 seconds. what is the acceleration of the car after 12.0 seconds?

The problem gives us the value for the initial velocity of the race car, and the time it takes for the race car to come to a complete stop. The question however, proves to be tricky. The question states as follow: "what is the acceleration of the car after 12.0 seconds?" Since it was already established that the car has come to a halt in 12.0 seconds, therefore, the acceleration would have to be 0, as the car would not be moving at all.
