The 300-lb block shown in the figure is kept from sliding down the inclined plane by friction and a force of smallest magnitude F. If the coefficient of friction between the block and the inclined plane is 0.4, then the magnitude of the frictional force is 0.4N, where N is the magnitude of the normal force exerted on the block by the plane. If the system is in equilibrium, use Cramer's rule to solve for F and N.

An airplane in flight is subject to an air resistanceforce proportional to the square of its speed v. But there is an additionalresistive force because the airplane has wings. Air flowing over thewings is pushed down and slightly forward, so from Newton’s third lawthe air exerts a force on the wings and airplane that is up and slightlybackward (Fig.). The upward force is the lift force that keeps theairplane aloft, and the backward force is called induced drag. At flyingspeeds, induced drag is inversely proportional to v2, so the total airresistance force can be expressed by Fair = av2 + b/v2, where a andb are positive constants that depend on the shape and size of the airplaneand the density of the air.
