The path of a cannonball is a parabola modeled by the equation y= 55 + x - 0.002x^2, where x and y are both measured in feet. In this model, the cannonball starts at the point (0,55) and travels to the right. The ground is represented by the x-axis. Determine the horizontal distance traveled by the ball before it hits the ground.
