Re: [Phys-l] momentum and energy

Fine...I'll take care of the problem.  If people are going to jump on others 
for this kind of trivial thing (if the physics professionals here are 
confused by the symbols I used--heaven help us), then I see no point in 
posting anything to this group.  It has really become a haven for retired 
old profs who seem to have nothing better to do than nit-pick anything and 
everything.  It really is getting silly, and not worth the effort!  ;-(

to add)
