Calculate the ratio of the drag force on a jet flying at 950 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at two-fifths the speed and half the altitude of the jet. the density of air is 0.38 kg/m3 at 10 km and 0.67 kg/m3 at 5.0 km. assume that the airplanes have the same effective cross-sectional area and drag coefficient c.
