(but by what?). But I can't imagine how such a collision could happen.
I still don't understand the difficulty. This is nothing more than a very
ordinary inelastic collision.

Well I still can't imagine how to accomplish such a collision in real life.
Sure you can make up such a problem and put it at the end of the chapter,
but this is just the kind of thing to which I thought Leigh has been
objecting (despite his 'nasty' note on this)--problems with no meaning. If
someone can explain a simple mechanism for such a collision, I'll slink away
quietly. ;-(
Better, I think, you should have the two blocks stick together. You end up
with negative work done on each (via the previously used work/energy
theorem), but at least there is some kind of 'real' coupling mechanism that
we could examine in terms of the various work definitions and work/energy
theorems to see how the different views would interpret the collision.
