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

⇒  

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
