Walker, Halliday & Resnick — Force and Motion-II: Problem 39
39 Calculate the ratio of the drag force on a jet flying at 1200 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at half that speed and altitude. 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.
📝 Solution Approach
Given: 1200 km, 10 km, 0.38 kg, 0.67 kg, 5.0 km
