I don't remember learning this concept in class..? (fps and heigth)

The equation y=-16t^2-60t+54 describes the height (in feet) of a ball thrown downward at 60 feet per second from a height of 54 feet from the ground. In how many seconds will the ball hit the ground? Express your answer as a decimal rounded to the nearest hundredth.
