Suppose that a movie is being filmed. An action shot requires an object to be thrown upward with an initial velocity of 48 feet per second off the top of the plaza, a height of 640 feet. The height h(t) in feet of the object after t seconds is given by the function h(t) = – 16t2 + 48t + 640. Determine how long before the object strikes the ground. (Hint: Let the height, h(t), be 0 and solve for t.)
