A damped mass/spring system takes 14.0 s for its amplitude of the oscillator to decrease by a factor of 9. By what factor does the energy of the mass/spring system decrease over that time?

The correct answer is "0.246".

Explanation:

Given that the amplitude is decreased by a factor of 9, then

As we know,

Energy will be:

⇒  

and,

⇒  

⇒  

On putting the estimated values, we get
