The graph shows for a mass-on-spring oscillator. At which instant is the mass at one of the <strong>amplitude positions</strong> (largest displacement)?
- A
- B
- C
- Dcheck_circle
Explanation
At the amplitude (turning points), velocity equals zero. On the graph the first zero after is at (where is at a minimum of the cosine — actually starts from going negative; zero at corresponds to max negative displacement). Any zero- instant works; is one such time.
