t= 1/4 (sqrt of 1400) = 1/4 ( sqrt of 700 * sqrt of2)
= 1/4 (sqrt of 100 * sqrt of 7* sqrt of 2)= 1/4(10 sqrt of 14)
= 1/4(10* 3.74165...)=1/4 * 37.4165= 9.354125 secs = approximately 9.36 seconds

1. T squared = S / 16. (Found by squaring the equation)
2. T squared = 1400 / 16. ( S = 1400 feet.)
3. T = The square root of {(1400 / 16)= 87.5} = ~9.2 seconds. (Taking the square root of each side of the equation.)

following the given formula
t=1/4(sqrt1400)
=1/4*37.42
=9.36 sec
