Farah wants to move a 40.0kg rable. She applies a force of 520N. Under these conditions, the table initially moves with an acceleration of 4.50 m/s^2 Calculate the friction force on the table

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.
