1.Consider a wing traveling at a velocity V , with a span equal to 20 c, where c is the cord length. Given the lift coefficient of 2.0 at a zero angle of attack, find the strength of the bound vortex, and the velocity at which the trailing vortices move downward under their own induced velocity field.

2.An airplane with a weight of 10,000lb/f is flying at 600ft/s at36,000ft., where the airplane pressure is 3.3 p.s.i.a. and thetemperature is -67 degrees F. The lift coefficient is 0.2. The spanof the wing is 54 ft. Calculate the wing area and minimum induced drag.
