A E 4 time (s) time (s) The plots above represent the oscillation mass on a spring. Refer to these plots for of a the next four questions, 20. For this particular mass spring system, the equilibrium position is a) 0 m b) 1 m c) 3 m d) 5 m 21. The amplitude of the position oscillation is a) 1 m b) 2 m c) 3 m d) 4 m e) 5 m 22. The phase relationship between the position and the velocity is (Note: 1 cycle 360°) a) The position is 1/4 cycle ahead of the velocity. b) The position is 1/4 cycle behind the velocity c) The position is 1/2 cycle ahead of the velocity. d) The position is 112 cycle behind the velocity e) None of the above. 23. The frequency of the oscillation is a) 2 s. b) 0.5 s c) 2 Hz. d) 0.5 Hz. e) It depends on whether you are asking about the position or the velocity
