You are performing an experiment with a
very long, uniform, taut nylon rope-such
as is being laid out in Fig. 16.10.1. In your
experiment, the rope is horizontal when in
equilibrium. One end of the rope passes
over a massless, frictionless pulley and
holds an anchor of mass M. The other end
of the rope is connected to a motor that
moves perpendicular to the long direction
of the rope with simple harmonic motion-
see Fig. 16.10.2. The motor's maximum
displacement from equilibrium is 5.00 cm,
and it moves with a frequency of 27.0 Hz.
In so doing, the motor does work on the
rope at an average rate if 100 J/s. The
mass per unit length of the rope is
M =
78.0 g/m.
