The motion of a particle executing simple harmonic motion is described by the displacement function, x(t) = A \cos (ωt + φ ). If the initial (t = 0) position of the particle is 1 cm and its initial velocity is ω cm/s, what is its initial phase angle. The angular frequency of the particle is π s−1{{s}^{-1}}.
