A copper rod (length = 2.5 m, radius = 1.60 10-3 m) hangs down from the ceiling. A 8.8-kg object is attached to the lower end of the rod. The rod acts as a "spring", and the object oscillates vertically with a small amplitude. Ignoring the rod's mass, find the frequency f of the simple harmonic motion. Hz
