A rock is thrown directly upward with an initial velocity of 118 feet per second from a cliff 275 feet above a beach. The height of the rock above the ground h after t seconds, is given by the equation h=−16t2+118t+275. When will the rock be 446 feet above the ground? If you have more than one answer, separate them with a comma. If necessary, round to 2 decimal places
