Solve the all parts of following question:
Question: A body oscillates with simple harmonic motion according to x = (12.5 m) cos[(2.0pirad/s)t + pi/3 rad].
Part A: At t = 3.00 s What is the displacement?
Part B: What is the velocity?
Part C: What is the acceleration?
Part D: What is the phase of the motion?
Part E: What is the frequency?
Part F: What is the period of the motion?
I would really appreciate some help for above question.
