Question
The figure below shows the displacement of a simple harmonic oscillator as a function of time. (The grid spacing on the t-axis is 5 s and on the y-axis is 25 cm.)
(a) Find the period, frequency, and amplitude of the oscillator.
period = s
frequency = Hz
amplitude = cm
(b) At what time(s) does the acceleration have its largest positive value? (Select all that apply.)
5 s 10 s 15 s 20 s 25 s 30 s 35 s 40 s
(c) When does the acceleration have its most negative value? (Select all that apply.)
5 s 10 s 15 s 20 s 25 s 30 s 35 s 40 s
Explanation / Answer
a) Period = 20 s, frequency = 0.05 Hz, amplitude = 50 cm.
b) Acceleration is max positive at negative amplitude positions: 15s and 35s
c) Acceleration is max negative at positive amplitude positions: 5s and 25s
