Amplitude of a mass-spring system, which is executing simple harmonic motion decreases with time. If mass = 500g, Decay constant = $\displaystyle 20$ g/s then how much time is required for the amplitude of the system to drop to half of its initial value ?
( $\displaystyle \ln 2=0.693$ )
Official answer
(1)
34.$\displaystyle 65$ s
