What do you mean by "traveling on the x axis"? If the circle is moving (and, for a while, passing through the parabola), how can there be "the [one] point" of intersection?I need to find the point at which the parabola y=x^2 and a unit circle traveling on the x axis from the right intersect.
So the circle was "rolling"... with its center on the x-axis? with its "bottom" on the x-axis?It stops at the parabola and intersects it at a point. Say it was rolling and it stopped when it hit y=x^2.
