**[SOLVED] Pendulum Oscillations Problem**

A very light rigid rod with a length of 0.500 m extends straight out from one end of a meter stick. The stick is suspended from a pivot at the far end of the rod and is set into oscillation.

(a) Determine the period of oscillation. (Hint: Use the parallel-axis theorem)

(b) By what percentage does the period differ from the period of a simple pendulum 1.00 m long?

I tried solving for period by using t=2(pi) sqrt(L/g) but that didn't work. It says to use the parallel axis theorum but I don't know what to do once I find I. Also, I don't think I can solve the second part until I get the first period, but once I do that would it just be T=2(pi) sqrt(L/g) for the period of the pendulum with 1m length?
