Question 14
Question MCQ▾
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 at its natural length. A third identical block C also of mass m moves on the floor with a speed v along the line joining A and B and collides with A. Then
(1) The kinetic energy of the A - B system at maximum compression of the spring is
(2) The maximum compression of the spring is
(3) The kinetic energy of the A – B system at maximum compression of the spring is zero.
(4) The maximum compression of the spring is
