An aircraft performs a maneuver called an aileron roll. During thismaneuver, the plan turns like a screw as it maintains a straightflight path, but using its ailerons to set the wings in circularmotion. Due to the structural strength of the material used to makethe wings, the airplane can only withstand an acceleration of 6.1m/s2 on the tips of its wings. If each wing is 3.0 m long, what isthe shortest time it can make a full turn when it performs anaileron roll?
