The mass of a truck with its cargo is 1800 kg. the truck is coasting to the right with a speed of 10 m/s. as it coasts its cargo of mass 300 kg is lifted up out of the truck by a crane. what will the velocity of the truck be after its cargo is taken off?

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.
