Question

An airline pilot calculates lift using the formula below, where L is the lift, d is the density of the air, v is the velocity of the aircraft, s is the wing area of the aircraft, and a is a value determined by airfoil and pitch angle. Find the lift of a 747 where d is 1.2 kg/m3, v is 831 ft/sec, s is 511 m2, and a is 0.002. Use L=1/2dv^2sa
