In the figure, two particles, each with mass m = 0.86 kg, are fastened to each other, and to a rotation axis at O, by two thin rods, each with length d = 5.4 cm and mass M = 1.2 kg. The combination rotates around the rotation axis with angular speed ω = 0.33 rad/s. Measured about O, what is the combination's (a) rotational inertia and (b) kinetic energy?

The figure shows a rigid assembly of a thin hoop (of mass m = 0.14 kg and radius R = 0.11 m) and a thin radial rod (of length L = 2R and also of mass m = 0.14 kg). The assembly is upright, but we nudge it so that it rotates around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in...
