Newton's Yo Yo - A real physics challenge!

Newton's Yo-Yo: a favorite physics toy! Newton's 3rd Law states that action force equals opposite reaction force- here the green and pink spheres have equal mass, so the forces of each collision provide accelerations that are equal and opposite such that the deceleration of the incoming sphere is equal to the acceleration of the outgoing sphere and the spheres trade places leaving one always at rest.
