The function x = (6.0 m) cos [(3 rad/s)t + /3 rad] gives the simple harmonic motion

The function x = (6.0 m) cos [(3π rad/s)t + π/3 rad] gives the simple harmonic motion of a body. At t = 2.0 s, what are the

(a) Displacement,

(b) Velocity,

(c) Acceleration, and

(d) Phase of the motion? Also, what are the

(e) Frequency and

(f) Period of the motion?
