Find the Xcm of center of mass of a barbell consisting of 50kg and 80kg weights at the opposite ends of a 1.5-along bar of negligible mass. [Hint] Choosing the origin at one the masses here conveniently makes one of the terms in the sum Sigmam_(i)x_(i)zero . But, as always, the choice of origin is purely for convenience and doesn't influence that actual physical location of the center of mass.
