Repulsion objects using laser. http://knol.google.com/k/paradox-of-classical-mechanics-2#Repulsion_objects_using_laser(2E) All explanation of this effect has a little problem. The spring should have very little weight.The ideal spring may have mass zero, but it's just an ideal model Is it possible make the spring is weightless on real world?
The answer is - YES. it just need replace mechanic spring by photons. The photons have and impulse, however the stationary mass of them is zero.
This diagram shows this repulsion using laser ray.
The laser itself has two rays with same intensive in opposite detections to each other. The net momentum for for laser is equal zero. However, these rays hit two cylinders with different alignment relatively to rays position.
Is it was described before these cylinders with same mass will have a different translational velocities.
