A large pendulum has 10 m length and it has a mass of 50 kg attached to that. The pendulum is oscillating in an under-damped condition. The initial amplitude of the oscillation is 1.2 m and it drops to 0.90 m after 5 days. Calculate the time it takes for the total energy of this pendulum to drop by 1/10 factor.
