Keyboard Shortcuts You were asked to solve for the unknown variable in the following problem. 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 250 square feet is 2,200 pounds when the plane is going at 250 miles per hour. Find the lifting force if the speed is 170 miles per hour. Round your answer to the nearest integer if necessary
