<PRE><B>Question 271673</B>
V equals the vertical leap.
T equals the hang time.


The formula is V = 48T^2


V = 30 inches.


Formula becomes:


30 = 48T^2


divide both sides of this equation by 48 to get:


30/48 = T^2


take the square root of both sides of this equation to get:


T = sqrt(30/48)


Use your calculator to solve to get:


T = .790569415 seconds.</PRE>
