I was always the classsmartass, esp in physics. In high school my
physics tchr marked me wrong on a test for Heisenberg's uncertainty
principle, where I said it was position and momentum (not velocity). I
argued mightily I was correct to no avail til he told me to shut up. So
I went to the library after school and looked in about 15 physics books,
which were pretty much evenly split on the two answers. So next day I
come in with all this, and before I could say anything he grabbed the
test and fixed the score and told me I was a smartass. I said, "Thank
you!" and the class all laughed like hell. I kept up with him for
awhile, he was a funny guy. He was also quite a large gent, and because
of his name we nicknamed him "Buzz" and had a saying that Budweiser
makes Buzzwider...
One day we had a substitute, a really old retired college prof, I think
he was German or East European of some sort, who proceeded to teach us
about the pervading "ether."

It's an inelastic collision, so what applies is,
1 2 1 2
--- m v = --- m v
2 1 1 2 2 2
Yes, you're right. I was thinking about my answer while driving home from
work last night and realized my answer was wrong.
In an INelastic collision, energy is NOT conserved, though momentum is, as
you initially wrote. Sorry for the mistake. (And I have a Ph.D. in
physics! Hangs head in shame ... :-) )
