Suppose that the terminal speed of a particular sky diver

Reference no: EM13542526

Suppose that the terminal speed of a particular sky diver is 165 km/h in the spread-eagle position and 305 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 (Aslower / Afaster).
