1. The problem statement, all variables and given/known data
1. A man's superelastic suspenders catch on a fence post, he flies back and forth, oscillating with an amplitude A. What distance does he movee in one period ? What is his displacement over 1 period 2. Relevant equations x=Acos(wt) 3. The attempt at a solution I know that the displacement is 0 since he returns to the original position. I also know that the distance should be 4A but I don't know how to explain it. It just makes sense to me. How do I prove that distance is 4A ?

What do you mean by n ?
If you mean n/2 by the angle then it will move A for each n/2 and there are 4n/2 so it moves 4A

Harmonic Oscillation
The font doesn't show it clearly but π is pi.
