Finding the path of an oscillating string

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving the oscillation of a string, specifically focusing on the amplitude and frequency of the oscillation. Participants are trying to interpret the phrasing of the problem, particularly the meaning of "pass a point of 0.2 minutes."

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Some participants express confusion regarding the wording of the problem, questioning the meaning of "0.2 minutes" as it relates to a point in time. Others suggest that the intended question might be about the displacement of the point after that duration, assuming an initial displacement of zero.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem's wording. There is no explicit consensus, but some guidance has been offered regarding the potential meaning of the time reference in the context of displacement.

Contextual Notes

Participants note that the original problem statement may have issues with translation or clarity, which could affect understanding. There is also mention of the problem being relayed from a student in Ukraine.

Homework Statement
The amplitude of the undamped oscillation of the point of the string is 1 mm, and the frequency is 1 kHz. What path will pass a point of 0.2 minutes?
Relevant Equations
V=f x lamda

I don't understand the question. Please help

The wording of the problem makes no sense at all. For one thing "pass a point of 0.2 minutes" is nonsense. "0.2 minutes" is not a point. Do you have the EXACT wording of the problem? Is this being translated into English from another language?

I agree
A student of mine who went to Ukraine asked me this
I'll ask him ok
Thank you very much
 
Here's a guess: they want the displacement of the point after 0.2 minutes. But you have to assume the displacement is zero at the start.
