The Pendulum (hard)

  1. Feb 19, 2006 #1
    I can't figure this one out:

    A point of the surface of a solid sphere (radius = R) is attached directly to a pivot on the ceiling. The sphere swings back and forth as a physical pendulum with a small amplitude. What is the length of a simple pendulum that has the same period as this physical pendulum? Give answer in terms of R.

    Thanks for the help
