Question

3. The displacement of a particle executing simple
harmonic motion is given by

y=A0 + A sinwt+B coswt.
Then the amplitude of its oscillation is given by​

Answer 1

the mean position of the particle is at y=Ao

the maximum displacement of the particle is ymax=Ao + √(A^2+B^2)

so amplitude is √(A^2+B^2)
