Calculate the ratio of the drag force on a passenger jet flying at an altitude of 10 km to the drag force on a prop-driven plane flying at two-fifths the speed and half the altitude of the jet. at 10 km the density of air is 0.380 kg/m3 and at 5.0 km it is 0.670 kg/m3. the prop-driven plane has one-third the cross-sectional area of the passenger jet. the passenger jet has two-fifths the drag coefficient of the prop-driven plane.
