Question 885591: A rock is thrown upward with an initial velocity of 68 fps from the top of a building that is 148 feet tall. The height h(ft) at any time t (sec) can be determined by the equation h(t) = -16t2 + 68 t +148. After how many seconds will the rock hit the ground? Answer by Alan3354(69443) (Show Source):
