A mass oscillating up and down while attached to the bottom of a spring can be modeled using simple harmonic motion. If the weight is displaced from its equilibrium position a maximum of 7 centimeters and it takes 3 seconds to complete one cycle, answer the following questions: Amplitude: Period: Frequency:

(1) Answers

Amplitude is the maximum displacement so 7 cm Period is the time taken to complete one cycle so 3 seconds Frequency is the inverse of time period, or the number of cycles per second so 1/3 = 0.33 Hz
