Suppose a rock is thrown upward from the top of a 256-foot tall building at an initial velocity of 96 ft/sec. The height h(t) of the rock in feet after t seconds is given by the function, h(t) = −16t2 +v0t + h0, where v0 is initial velocity and h0 is initial height. How long does it take the rock to hit the ground, neglecting air resistance?
8 seconds
