A coin is thrown straight up from the level of the roof of a 216-foot tall building with an initial velocity of 18 ft/sec assuming no air resistance; the height of the coin at any given time is given by the function,h (t) = -18t² + 18t + 216, where h(t) is in feet and t is in seconds. Determine the time it took the coin to hit the ground. 2 seconds 3 seconds O 4 seconds O 7 seconds
