You are driving on a straight road at exactly 21.8 miles per hour when you see a child run out in front of your car, chasing a ball. You push the brakes hard, which results in an acceleration of exactly -36000 miles/hour2. The child freezes in panic and you cannot swerve to avoid the child because there are cars parked on both sides of the street.

How many feet does your car travel before it comes to a complete stop?

Your answer should be accurate to the nearest foot.
