Question 1036012: A model rocket is launched from the roof of a building. It's flight path is b modeled by h=5t^2+40t+100 where h is the height of the rocket above the ground in meters and t is the time after the launch in seconds. At what time did the rocket reach its maximum height? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! h=-5t^2+40t+100. Note the editing of -5t^2
maximum height is vertex, which is -b/2a (that is value of t)
-40/-10=4
at 4 seconds, the rocket will reach maximum height.
