(Of course the CM will be accelerating all the while.)

    I should be able to prove this to you using Physics given some time (I can't do it "off the cuff" as it were) but the logical argument above should be easy enough to see. If you need a more Mathematical answer I ought to be able to provide it. Let me know.

    If you are anyone else could prove this using physics that would be helpful as that is what I actually need. Pertaining to Planar Kinematics and Kinetics of a Rigid Body.. Force..Acceleration etc...
