A ball is thrown from a height of 123 feet with an initial downward velocity of 11/fts . The ball's height h (in feet) after t seconds is given by the following.

h= 123-11t-16t^2 How long after the ball is thrown does it hit the ground? Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.)
