The terminal speed of a sky diver is 140 km/h in the spread-eagle position and 346 km/h in the nosedive position. Assuming that the diver's drag coefficient C does not change from one position to the other, find the ratio of the effective cross-sectional area A in the slower position to that in the faster position.

The terminal speed of a sky diver is 140 km/h in the spread-eagle
position and 346 km/h in the nosedive position. Assuming that the
diver's drag coefficient C does not change from one position to the
other, find the ratio of the effective cross-sectional area A in the slower
position to that in the faster position.

Chapter 06, Problem 039
Calculate the ratio of the drag force on a jet flying at 1020 km/h at an
altitude of 9.5 km to the drag force on a prop-driven transport flying at
half that speed and altitude. The density of air is 0.41 kg/m3 at 9.5 km
and 0.68 kg/m³ at 4.8 km. Assume that the airplanes have the same
effective cross-sectional area and drag coefficient C.
