if you drop it:
A human body in free fall in the Earth's atsmophere will attain a a speed that will not increase, this happens when the drag of the air equals the pull of gravity, it is usually around 120 miles per hour.
The acceleration of gravity is 9.8 m/s^2 and in the absence of other forces falling objects would always gain 9.8 m/s of velocity for every second of fall. However, the faster you move through the atmosphere, the larger the retarding force due to air resistance. At some speed (called "terminal velocity") this retarding force is equal to the force of gravity, and an object moving at terminal velocity falls at nearly constant velocity.

Anyone else have any luck?
