- Determine the deviation at a time when the amplitude has

dropped to 1/5 of the original value.

- Relevant Equations
- A=A0 e^-bt

Hi !

Problem :

y = 5 e^-0.25t sin (0.5.t) (m, s). Determine the deviation at a time when the amplitude has

dropped to 1/5 of the original value.

I tried with A=A0 e^-bt=5 e^-0.25t

- Do i need to determine the time here or recreate the deviation equation when A decreased ? I don't understand the meaning of the question .
