Skydiving terminal velocity. When determining the terminalvelocity of items in free fall, the friction factor f is typicallycalled the drag coefficient and is represented by the symbol CD.They are really the exact same thing. Consider a human beingjumping from an airplane at a sufficient altitude to achieve aterminal velocity. There is quite a bit of literature regardingvalues of the drag coefficient for various scenarios. Assume thefollowing in known for CD:

0.69 = human falling vertically, feet first.
1.05 = human falling horizantally, arms and legs spread out. 1.75 =human falling with an open, functioning parachute.

Determine typical values/estimates for terminal velocities foreach of the cases de- scribed. Clearly state your assumptions foreach case.
