d=.5 a t^2 d is 200 ft, a is 32 ft per sec^2 and t is solved for
400/32= t^2 25/2= t^2 or t= 3.54 seconds
The persons weight is not important

The last answerer was right. Just thought I would add that it wouldn't make much difference whether it was a 100lb woman or a 300lb man. Air resistance and shape wouldn't play much of a part in only 200 ft.
Happy new year!

Whoops, just saw where the guy above me did mention that. Oh well, too much sparkling apple juice tonight!

about 3.5 seconds. The formula for determining the length of a drop is 16x^2. So you square 3.5=12.25 then 16(12.25)=196 ft.
Close enough?

2.5 seconds.
Unless Terminal Velocity is a consideration, the rate of acceleration is 32ft/s^2.
At the first second, his speed will be 32 ft/s. At the second, his speed will be 64 ft/s and so on...

A fraction over 6 seconds.

This is a physics question.
