A student wants to design a toy airplane that can fly the farthest possible distance. The design needs to take into account the drag force and lift force. Assuming a constant velocity, what shape and size should the wings of the airplane be to minimize the drag force and maximize the lift force? Use the principles of fluid mechanics to solve this problem.
