How Fast Is Terminal Velocity?

Answer

A free falling object achieves its terminal velocity when the downward force of gravity (Fg) equals the upward force of drag (Fd). Mathematically, an object asymptotically approaches and can never reach its terminal velocity. Terminal velocity is said to be is about 195 km/h (120 mph or 55m/s).

1 Additional Answer
There is no one given number for terminal velocity. It is determined by the way an object is shaped. For example a skydiver can change his terminal velocity by changing the form he takes. You can find more information here: http://www.newton.dep.anl.gov/askasci/phy00/phy00800.htm
