An arrangement of two blocks placed one above the other is shown. There is no fricition any where. A horizontal force `F` acts on one of the blocks as shown. It is required to calculate the acceleration of centre of mass.

Minimum horizontal force (F) required to move the block shown in diagram is__

Two blocks of masses m_(1) and m_(2) are connected by an ideal sprit, of force constant k . The blocks are placed on smooth horizontal surface. A horizontal force F acts on the block m_(1) . Initially spring is relaxed, both the blocks are at rest. What is acceleration of centre of mass of system at the instant of maximum elongation of spring
