a rigid assembly of a thin hoop (of mass m and radius R = 0.200 m) and a thin radial rod (of mass m and length L = 2.50 R). 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?
im kinda stuck.

Not a very good question. You need to give several more pieces of information and modify your assumption. The exact orientation or the rod and hoop must be known (In relation to each other). Also the only thing that could create angular speed is the nudge (assuming the assembly was at rest to start). To ignore the nudge is not possible.
