Physics - SHM Question with Solution | TestHub

Two identical blocks$A$and$B$, each of mass$m$resting on a smooth floor, are connected by a light spring of natural length$L$and the spring constant$k$, with the spring at its natural length. A third identical block at$C$(mass$m$) moving with a speed ($v$) along the line joining$A$and$B$collides with$A$. The maximum compression in the spring is proportional to
