Traveling Waves Are Created on a Rope That Has a Mass

Multiple Choice

Traveling waves are created on a rope that has a mass per length 0.200 kg/m that is stretched with a tension of 400 N. If the end of the rope is moved up and down with simple harmonic motion with amplitude 30.0 cm and a period 1.40 s, how much work is done in one period of the motion?

A) 133 J
B) 400 J
C) 267 J
D) 11.3 J
E) No work is done because the tension pulls outward along the rope, but the end of the rope moves perpendicular to the rope.
