A ball is thrown from a height of 154 feet with an initial downward velocity of 10 ft / s. The ball's height h (in feet) after t seconds is given by the following.
h = 154 - 10t - 16t^2
How long after the ball is thrown does it hit the ground? Round the answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.)
t = ____ Seconds
