Question 203282: A rocket is launched from atop a 92 foot cliff with an initial vertical velocity of 112 feet per second. The height of the rocket t seconds after launch is given by the equation h= -16t^2+112t+92. Graph the equation to find out how long after the rocket is launched it will hit the ground. Estimate your answer to the nearest tenth of a second.

Graph:

When h (vertical axis) = 0, t = 7.75 approximately.
So the rocket will hit the ground (h = 0) in about 7.75 seconds after launch.
