A ball is projected from a point in a horizontal plane so as to strike a vertical wall at right angle at point \(A\) after rebounding from the wall it strikes the horizontal plane once and returns to the point of projection just before second collision at horizontal surface. Find the coefficient of restitution for the two collisions, \(\text{assuming it to be same for both the collision}\).
