Homework Help: intermediate algebra

Posted by jennifer on Thursday, November 6, 2008 at 12:51pm.

A projectile is launched directly upward from the top of a 112 - foot building with an initial velocity (speed) of 96 feet per second. This translates to the h(t) = -16t^2 + 96t + 112 where h(t) is the height of the projectile in feet and t is the time in seconds after it is launched. When will the projectile hit the ground?

t = 7 seconds after it is launched

Is this correct?
