Alarge ant is standing on the middle of a circus tightrope that is stretched with tension ts. the rope has mass per unit length μ. 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 λ and amplitude a. assume that the magnitude of the acceleration due to gravity is g. what is the minimum wave amplitude amin 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.
