Problem 3: [10 points] If P = (a,a2) is a point on the parabola y = r2, except for the origin, let Q be the point where the normal line at P intersects the parabola again (i.e. draw the tangent line at P, then draw a perpendicular line to this line through P, the other intersection point with the parabola is ). Show that the y-coordinate of Q is smallest when a =
