Solve the all parts of following problem given below:
Problem: The position of a particle in cm is given by x = (5) cos 5?t, where t is in seconds.
Part I: What is the frequency?
............. Hz
Part II: What is the period?
.............. s
Part III: What is the amplitude of the particle's motion?
.............. cm
Part IV: What is the first time after t = 0 that the particle is at its equilibrium position?
