-- If there were no air, and he was dropped from 200 feet, then he would
hit the ground 3.536 seconds later. (rounded)
-- If he were to fall through air, then the answer depends on the person's
size, shape, weight, clothing, and position during the fall.
(Recall that one sky-diver can catch another one by assuming the proper position
during the fall.)

It can take a long time of practice to be able to jump up and clap the feet together twice. It is best to practice on solid ground, so there is less of a chance of falling and getting hurt.
The shaddow would be 6.7 feet long (assuming flat ground)
A long time...

John should buy a post that is 10 feet long. This accounts for the 8 feet above ground level and the 2 feet that needs to be buried in the ground.

The acceleration of a free falling object is 32 feet per second per second. This is acceleration due to gravity. This is, of course, not the velocity of the falling object, but if you know a little bit more about the falling object you can figure out its velocity using constant acceleration formulas:: : : : For example:If you are standing on the top floor of the Eiffel tower, which is 896 feet above ground, and drop something out of the window, you can calculate how fast it is going just before it hits the ground using equation 4.vi = 0s-si=896 feeta=32 feet/second/secondPlugging in our values, we find that the object would be traveling at 239.466 feet/second.You could also figure out long it takes to reach the ground using either equation 2 or 3.This is, of course, an ideal case where there is no wind or air resistance.
No. You can have one foot on the ground or no feet on the ground as long as the player has secured the ball. ie. A player can signal for a timeout in mid-air as long as he/she has secured the ball and signaled for the timeout before stepping out of bounds.
