Question 1034538
the distance a free falling object has traveled can be modeled by the equation d= 1/2 at^2, where a is acceleration due to gravity and t is the amount of time the object has fallen. what is t in terms of a and d? 
------------
d = at^2/2
-----
2d = at^2
at^2 = 2d
t^2 = 2d/a
t = {{{sqrt(2d/a)}}}
