 Click here to see ALL problems on Quadratic Equations Question 442619: Hi, I have an algebra question that states the following: (not sure where to go with this) If h = -16t^2 + 48t represents the height of a rocket, in feet, t seconds after it was fired, when will the rocket hit the ground? It does give a hint: "The rocket is on the ground when h = 0" So it states that the rocket will hit the ground after _______ second(s). Answer by mananth(12270)   (Show Source): You can put this solution on YOUR website!At t=0, h=0, it is on ground before firing h=-16t^2+48 h =0 when it hits the ground after firing -16t^2+48=0 16t(-t+3)=0 /16 t(-t+3)=0 t= 0 OR t=3 It will hit after 3 seconds
