**drwls**, Friday, December 3, 2010 at 9:56pmAngular momentum will conserved, and the total moment of inertia (I) is tripled. Since angular momentum is I*w, the angular spped w must be reduced to 1/3 of the original value.

With w reduced to 1/3 of the original and I tripled, the kinetic energy (1/2) I w^2 will be reduced to 1/3 the former value.
