A large 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 free-fall acceleration is g.

What is the minimum waveamplitude Amin such that the ant will become momentarily weightless atsome point as the wave passes underneath it?
