Physics - SHM Question with Solution | TestHub

Two blocks $\mathrm{A}(3\mathrm{kg})$ and $\mathrm{B}(6\mathrm{kg})$ are connected by a spring of stiffness $512\mathrm{N}/\mathrm{m}$ and placed on a smooth horizontal surface. Initially the spring has equilibrium length. Velocity $1.8\mathrm{m}/\mathrm{s}$ and $2.2\mathrm{m}/\mathrm{s}$ are imparted to A and B in opposite direction. The maximum extension of the spring will be $\_\_\_\_$ cm.
