Homework Help Overview

The problem involves a scenario where a tightrope walker generates a sinusoidal transverse wave on a tightrope, with the goal of determining the minimum wave amplitude required for an ant standing on the rope to become momentarily weightless. The variables involved include tension (T), mass per unit length (u), wavelength (λ), and the acceleration due to gravity (g).

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to find a formula for amplitude and considers the implications of setting mass per unit length (u) to zero. They also inquire about the relationship between wave properties and amplitude, expressing confusion about how to derive or express amplitude in terms of the given variables.

Discussion Status

The discussion appears to be in an early stage, with participants seeking clarification and guidance on how to approach the problem. There is a lack of explicit consensus, and some participants are looking for additional input or resources.

Contextual Notes

One participant referenced a previous thread related to the problem, indicating that they may have found additional context or information relevant to their inquiry.

A large ant is standing on the middle of a circus tightrope that is stretched with (T) tension . The rope has mass per unit length (u). Wanting to shake the ant off the rope, a tightrope walker moves her foot up and down near the end of the tightrope, generating a sinusoidal transverse wave of wavelength (lamda) and amplitude (A) . Assume that the magnitude of the acceleration due to gravity is (g).

What is the minimum wave amplitude such that the ant will become momentarily weightless at some point as the wave passes underneath it? Assume that the mass of the ant is too small to have any effect on the wave propagation.
Express the minimum wave amplitude in terms of T, u, lamda, and g.


How should I approach this problem? Should I try to find a formula for Amplitude and plug in 0 for the mass/length (u)??


For the wave function of a traveling wave Asin[(k)x+(w)t] on a thin rope that what way can we determine the amplitude?

I know the amplitude is the height of the wave from rest to crest or rest to trough. But I cannot figure out anyway to show A.

For example like the wavelength (lamda) = 2pi/k

But what can Amplitude = ?


Thank you for your help.
