One reference book states that, after a large earthquake, Earth can be treated as an oscillator that has a period of 54 min and a quality factor of 400.
Part A
What percentage of the energy of oscillation is lost to damping forces during each cycle?
E0-E1E0 = %
Part B
What fraction of the original energy is left after 3.0 days?
E3.0dE0 = %
