## Homework Statement

A 82kg skydiver can be modeled as a rectangular "box" with dimensions 21cm× 44cm× 1.8m

## Homework Equations

v = sqrt(2mg/(rho * C *A))

## The Attempt at a Solution

A = 0.21 m * 0.44 m = 0.0924 m^2

v = sqrt(2 * 82 kg * 9.81 m/s^2 / (1.2 kg/m^2 * 0.0924 m^2 * 0.80))

=135m/s

Apparently this is wrong. I have tried many other formulae but I haven't had luck and I have one more attempt remaining. Any ideas?
