M6. A student measures the motion of a springmass oscillator and calculates a regression equation based on the oscillator's motion. That equation is x = 0.1cos(5.4t). The student takes down the amplitude and angular frequency from this equation. Which of the following can the student calculate from these two values? Select two answers. (A) Period of oscillation (B) Mass of the oscillating object {(W Qrino r'nnqtnnf n'F flap ahno
