<PRE><B>Question 390106</B>
The distance an object falls is directly proportional to the square of time it has been falling.  After 6 seconds it has fallen 1296 feet. How long will it take to fall 2304 feet?
----------------------
1296 = kt^2 = 36k
k = 36
------------
2304 = kt^2 = 36t^2
t^2 = 2304/36 = 64
t = 8 seconds
