a rigid assembly of a thin hoop (of mass mand radius R = 0.150 m) and a thin radial rod (of mass m and length L = 2.00R). The assembly is upright, but if we give it a slight nudge, it will rotate 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 such a nudge is negligible, what would be the assembly’s angular speed about the rotation axis when it passes through the upside-down (inverted) orientation?

Question
a rigid assembly
of a thin hoop (of mass mand radius
R = 0.150 m) and a thin radial rod
(of mass m and length L = 2.00R). The
assembly is upright, but if we give it a
slight nudge, it will rotate 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 such a nudge is negligible,
what would be the assembly’s angular speed about the rotation axis
when it passes through the upside-down (inverted) orientation?
