Question 1156020: Tyrone built a model rocket for his science project. The equation h= -16t2+260t models the flight of the rocket, launched from ground level at a velocity of 260 feet per second, where h is the height of the rocket in feet after t seconds. How long does it take the rocket to hit the ground?
