Find the rotational kinetic energy (in Joules) of the composite object in the figure. The axis of rotation is shown with a dashed line. The two thin rods are uniform and each has a length L= 1.0 m and mass M= 6.0 kg. The hoop has a radius L and a mass M. The hoop, the rods, and the axis of rotation are all in the same plane. rotating with angular velocity ω= 4.0 rad/s.

A nylon guitar string has a linear density of μ= 4.88 g/m and is under tensionτ= 144 N. The fixed supports are D= 90.8 cm apart. The string is oscillating in the standing wave pattern as shown in the figure. Calculate the frequency (in Hz) of the traveling waves whose superposition gives this standing-wave pattern.
