In the figure shown the spring is compressed by `'x_(0)'` and released . Two block `'A'` and `'B'` of masses `'m'` and `'2m'` respectively are attached at the ends of the spring. Blocks are kept on a smooth horizontal surface and released. Find the work done by the spring on `'A'` by the time compression of the spring reduced to `(x_(0))/(2)`.
