A box with a mass of 15.0 kg is being pushed on a level surface with a
horizontally applied force. It just starts to slide when 40.0 N is applied
and will continue to slide if 35.0 N is applied to the box. What is the
Normal Force (FN) acting on the Box?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
