Homework Statement
An ant with mass "m" is standing peacefully on top of a horizontal, stretched rope. The rope has mass per unit length "mu" and is under tension "F" .
Without warning, Throckmorton starts a sinusoidal transverse wave of wavelength "lambda" propagating along the rope. The motion of the rope is in a vertical plane.
What minimum wave amplitude will make the ant become momentarily weightless? Assume that "m" is so small that the presence of the ant has no effect on the propagation of the wave.
Express your answer in terms of the variables "m","mu","lambda","F" and appropriate
Homework Equations
lambda=2pi/frequency
k=omega/velocity
v=(F/mu)^1/2
The Attempt at a Solution
I have no idea where to start this problem. What must be true for the ant to be weightless? Please help
