Determine the lift if the speed is decreased

Reference no: EM13672785

The lifting force exerted on an airplane wing varies jointly as the area of the surface and the square of the planes velocity. The lift for a wing of area 120 sq.ft. is 2025 lb when the plane is going 90 miles per hour. Determine the lift if the speed is decreased to 80 mph.
