Answer:
0.05508 kg/sec
Step-by-step explanation:
mass of the oscillator m= 0.231 Kg
amplitude of oscillation given by

Ao= maximum amplitude
t= time and 1.00% of its initial value in t= 9.43 s.
A= 0.01Ao
⇒0.01=e^(-I×9.43)
ln100= 9.43×l
l=0.4883
we know that l= c/2m
c= damping constant
c= 2ml
=2×0.231×0.4883
=0.05508 kg/sec
