Calculate the ratio of the drag force on a jet flying at 899km/h at an altitude of 7.8 km to the drag force on a prop-driven transport flying at half that speed and altitude. The density ofair is 0.51 kg/m3 at 7.8 km and 0.73 kg/m3 at3.9 km. Assume that the airplanes have the same effectivecross-sectional area and drag coefficient C.
