The motion of a particle in S.H.M. is described by the displacement function, x=A cos(ωt+ϕ), If the initial (t=0) position of the particle is 1cm and its initial velocity is ωcms−1, what are its amplitude and initial phase angle ? The angular frequency of the particle is πs−1. If instead of the cosine function, we choose the sine function to describe the SHM : x = B sin(ωt+α), what are the amplitude and initial phase of the particle with the above initial conditions ?
