Here are some relationships that may be helpful: The position of an object undergoing simple harmonic motion along the x-axis is given by: x(t) = x m cos(ωt+φ) Its velocity in the x-direction is given by: v x (t) = - ω*x m sin(ωt+φ) And its acceleration in the x-direction is given by: a x (t) = - ω 2 x m cos(ωt+φ) In these equations x m is the amplitude, ω is the angular frequency, and φ is the phase angle.
