3. A damped oscillator's amplitude dec¡eases from 8 cm to 4 cm in 20 seconds, If the intial energy of the oscillator is 64 J, what is the energy âfter 40 seconds? (Recall: E: (l/2)kA2)

2. Relevant equations

not sure how to approach the problem

3. The attempt at a solution

intia E which is 64J = k*A^2 solve for k since 64 = K * 0.08^2. k = 9375 N

problem how do I take the damped oscillator into account for after 40 seconds

so after 40 seconds E = 9375*A^2 ??? or am i doing it wrong totally
