A football is kicked toward a goal post that is 10 feet high. The path of the football is modeled by the graph of y = -0.005x^2 + 0.6x where x and y are measured in feet. On a coordinate plane, the x-axis represents the ground, and the ball leaves the ground at the origin. The ball hits the goal post on the way down. How far from the goal post is the kicker? Explain.
