**Can someone clarify this please? Confusing Wording...**

**1.Two blocks, each with a mass 0.40 {\rm kg}, can slide without friction on a horizontal surface. Initially, block 1 is in motion with a speed v = 1.2 {\rm m/s}; block 2 is at rest. When block 1 collides with block 2, a spring bumper on block 1 is compressed. Maximum compression of the spring occurs when the two blocks move with the same speed, v/2 = 0.60 {\rm m/s}.**

**2.If the maximum compression of the spring is 1.9 {\rm cm}, what is its force constant?**

**3. Hi everyone, All I really need is clarification of the last given. It says "...blocks...move with the same speed, v/2 = 0.60 m/s"**

V/2 ? Does this just mean they are both now traveling .60m/s or is there something else I can derive from this that I am missing.

Thanks!
