document.write( "Question 1062177: While hovering near the top of a waterfall in a national park at 5184 ​feet, a helicopter pilot accidentally drops his sunglasses. The height h(t) of the sunglasses after t seconds is given by the polynomial function h(t)=-16t^2 + 5184. When will the sunglasses hit the​ ground?\r
