Fenway Park is a Major League Baseball park in Boston, Massachusetts. The park offers seats on top of the left field wall. A person sitting in one of these seats accidentally drops his sunglasses on the field. The sunglasses' height h, (in feet) can be modeled by the function h = -16t2 + 45 where t is the time (in seconds) since the sunglasses were dropped. The time it takes for the sunglasses to reach the field in seconds. (Round your answer to 3 decimal places)
