3. (10 pts) Suppose an airplane with its engine off has a maximum lift-to-drag ratio of 14, and its CL at max lift to drag ratio is 0.64. Its weight is 3,000 lb, and its wing area is 175 ft2. Determinea) The minimum glide angleb) The maximum range along the ground, starting from an altitude of 10,000 ft. c) When gliding at the minimum glide angle, determine the velocity at an altitude of 10,000 ft and at an altitude of 2,000 ft.
