Abody oscillates with simple harmonic motion along the x axis. its displacement varies with time according to the equation x = 5 sin (πt + π/3). what is the phase of the motion (in rad) at t = 2 s?

θ = (7π / 3) rad

Explanation:

given,

displacement of simple harmonic motion along x-axis

equation is given as

                   x = 5 sin (π t + π/3 )

general equation of simple harmonic motion

                   x = A sin θ

           θ is the phase angle

      θ = π t + π/3

at   t = 2 s

Phase of the motion at t =2 s is θ = (7π / 3) rad
