An aircraft performs a maneuver called an aileron roll. Duringthis maneuver, the plane turns like a screw as it maintains astraight flight path, by using its ailerons to set the wings incircular motion. Due to structural strength, an airplane can onlywithstand an acceleration of 4.0m/s^2 on its wing tips. If the wingspan is 8.9m, what is the shortest time it can make a full turnwhen it performs an aileron roll?

A.) 1.1s

B.) 5.0s

C.) 6.6s

D.) 9.4s
