<PRE><B>Question 562382</B>
The height of an object thrown upward with an initial velocity of 32 feet per second is given by the formula h=-16t^2+32t, where t is the time in seconds.  How long will it take the object to reach a height of 16 feet?
---------
h=-16t^2+32t
Solve for t then h = 16
h=-16t^2+32t = 16
t^2 - 2t + 1 = 0
t = 1 second.
