Thanks John.

I want to be sold on the momentum flow method so I am trying to see
what the advantage of it is. The short version of the force method
would be, "add the mass of a table-tennis ball to the left (the
internal forces don't matter) and push down hard on the right--the
right goes down." I got the impression that a short movie with little
down arrows flowing into and out of the beakers flashed into your mind
and you immediately saw the little down arrows flowing into the beaker
on the right faster. I wanted to see that movie.
I'd like to see the movie, too ... but I've never seen it.
Maybe some day I can make the movie, but the movie does not make itself.
