+d%2F16+=+t%5E2+
+d+ is in ft and
+t+ is in sec
Given:
+d+=+64+
-----------------------
+64%2F16+=+t%5E2+
+4+=+t%5E2+
Take the square root of both sides
+2+=+t+
It takes 2 sec to fall 64 ft

Let me show you how to write the equation correctly:


    d = 16*t^2,


where t is the time in seconds and d is the falling distance in feet.
