A long-range jet liner flies (almost exactly) level at constant speed, subject to the forces of drag fD=(1/2)CDrhoSv^2, thrust Ft, and weight Mg. Given the plane's wing area, lift and drag coefficients, speed and takeoff mass, calculate the engine power required for level flight during the cruise phase of its long nonstop flight, as a function of distance traveled. Numerical evaluation of all coefficient in your result will be required.
