1. The problem statement, all variables and given/known data
A sinusoidally varying driving force is applied to a damped harmonic oscillator of force constant k and mass m. If the damping constant has a value b_1, the amplitude is A_1 when the driving angular frequency equals sqrt (k/m). In terms of A_1, what is the amplitude for the same driving frequency and the same driving force amplitude F_{max}, if the damping constant is 3b? In terms of A_1, what is the amplitude for the same driving frequency and the same driving force amplitude F_{max}, if the damping constant is (1/2)b? 2. Relevant equations A= (Fmax/(sqrt(kmw^2)^2+(b^2w^2)) w= omega 3. The attempt at a solution I try to put in the the b values but it is saying it is incorrect. 1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution

I got the answers they are
(1/3) A_1 and 2A_1
