A block A resting on a smooth horizontal plane is attached by threads to a point P and, by a weightless pulley, to a block B of the same mass, m. A is also attached to a point O by a spring of length l0 and spring constant k = 5m(g)/(l)0. The thread PA is cut and block A starts moving.
1. Find the distance at which block A breaks off the plane.
2. Find its velocity at the moment it is breaking off the plane.
