What is the logarithmic decrement of damping Λ of damped harmonic oscillator, if its mechanical energy decreases to the 50% of its initial value during first 10 seconds? The period of oscillations is T=2s.

Mechanical energy is proportional to the amplitude squared so if the ratios of energies is 1 2 , the ratio of amplitudes will be 1 2 then:
δ = 1 5 l n 1 1 2 = 1 5 l n 2 = 0.0693
