Suppose an object is dropped from a height h0 above the ground. Then its height after t seconds is given by h = 16t2 + h0, where h is measured in feet. Use this information to solve the problem. A ball is dropped from the top of a building 86 ft tall. (Round your answers to three decimal places.) (a) How long (in s) will it take the ball to fall half the distance to ground level? Incorrect: Your answer is incorrect. s (b) How long (in s) will it take the ball to fall to ground level? Incorrect: Your answer is incorrect. s
