Calculate the ratio of the drag force on a jet flying at 962 · m/ℎ at an altitude of 9.00 m to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is 0.438 · /m³ at 9.00 m and 0.699 · /m³ at 4.50 m. Assume that the airplanes have the same effective cross-sectional area and drag coefficient .
