Your school science club has devised a special event for homecoming. you've attached a rocket to the rear of a small car that has been decorated in the blue-and-gold school colors. the rocket provides a constant acceleration for 9.0s. as the rocket shuts off, a parachute opens and slows the car at a rate of 5.0m/s2. the car passes the judges' box in the center of the grandstand, 990m from the starting line, exactly 12s after you fire the rocket.
