Abuilding that is 105.50 ft. feet tall is casting a shadow that is 37.50 ft. feet. if the building next to it, is casting a shadow of 41.00 ft. feet, how tall is that building?

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.
