To perform a maneuver called an aileron roll, an airplane pilot uses the ailerons to set the wings in circular motion. The airplane turns like a screw as it maintains a straight flight path. Due to structural strength, an airplane can only withstand an acceleration of on its wing tips. The wing span of this airplane is 8.9 m. What is the shortest time it can make a full turn during an aileron roll?
