Question:

It has been stated that the vibrating earth has a resonance period of 54 min and a Q factor of about 400 and that after a large earthquake, the earth “rings” (continues to vibrate) for about 2 months.

(a) Find the percentage of the energy of vibration lost to damping forces during each cycle.

(b) Show that after n periods, the energy is En = (0.984)nE0, where E0 is the original energy.
