Suppose an object is dropped from a height h0 above the ground. Then its height after t seconds is given by h = - 16t 2 + h 0, where h is measured in feet. A ball is dropped from the top of a building 95 ft tall. How long will it take to fall to ground level? Round your answer to two decimal places. • t = 1.72 seconds • t = 2.44 seconds • t = 0.95 seconds • t = 2.96 seconds
