During a physics experiment, a class drops a golf ball of a bridge toward pavement below. The bridge is 75 ft high. The function h = -16t^2 +75 gives the golf ball's height h in feet above the pavement after t seconds. Use the graph of the function at the right. After how many seconds does the golf ball hit the pavement?
