A smaller bar A resting on a smooth horizontal plane is attached by threads to a point P and by means of a weightless pulley to a weight B possessing the same mass as the bar itself Besides the bar is also attached to a point O by means of a light non deformed spring of 5mg length and stiffness k where m is the mass P A 10000 0000 10 10 B of bar The thread PA having been burned the bar starts moving Find its velocity at the moment when it breaking off the plane
