ball is thrown upward with an initial velocity of 28 meters per second from a cliff that is 80 meters high. The height of the ball is given by the quadratic equation h = -4.9t 2 + 28t + 80 where h is in meters and t is the time in seconds since the ball was thrown. Find the time it takes the ball to hit the ground. Round your answer to the nearest tenth of a second
