I am stumped on this problem. If anyone can help it would be greatly appreciated. A plane is approaching an airport in a traffic holding pattern. While awaiting its clearence to land, the plane traverses a horizontal circle of radius 2520 meters at constant speed, Each complete turn of the circle delays the scheduled landing by another 2.5 minutes. Assume that the direction of the lift force exerted on the plane by the air is exactally perpendicular to the wing surface. Please determine, to three significant figures, the angle at which the crew must bank the plane with respect to the horizontal, in order to accomplish these turns.
