Physics - SHM Question with Solution | TestHub

Comprehension (Figure 5.124): Two identical blocks $P$ and $Q$ of mass $m$ are attached to two identical springs (constant $k$), initially unstretched. The blocks are initially in contact. The left spring (with $P$) is compressed by $A/2$ and the right spring (with $Q$) is compressed by $A$. Both blocks are then released together. The speed of block $Q$ just before $P$ and $Q$ are about to collide for the first time is:
