The lifting force, F, exerted on an airplane wing varies jointly as the area, A, of the wing's surface and the square of the plane's velocity, v. The lift of a wing with an area of 140 square feet is 27,600 pounds when the plane is going at 220 miles per hour. Find the lifting force if the speed is 100 miles per hour. Round your answer to the nearest integer if necessary. Answer Keypad
