The terminal speed of a sky diver is 163 km/h in the spread-eagle position and 325 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.
Answers: 1
, where m is the mass of the sky diver, g the gravitational acceleration, 
the air density, A the effective cross-sectional area and 
the drag coefficient.
and realize that for both situations the right hand side of that formula will be the same. This means that 
, so the ratio of the effective cross-sectional area A in the slower position (
for 
) to that in the faster position (
for 
) will be
