Two blocks A and B each of mass m are connected by a massless spring of natural length L and spring constant k. The blocks are initially resting on a smooth horizontal floor with the spring in its natural length, as shown in figure.
A third identical block C, also of mass m moves on the floor with a speed v along the line joining A and B collides with A, elastically. Then,
The kinetic energy of the AB system at maximum compression of the spring is mv2.
The maximum compression of the spring is
