A28 kg child goes down a straight slide inclined 38∘ above horizontal. the child is acted on by his weight, the normal force from the slide, kinetic friction, and a horizontal rope exerting a 30 n. how large is the normal force of the slide on the child? if the child slides with a constant speed, how large is the kinetic frictional force from the slide?

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.
