The figure shows a rigid assembly of a thin hoop (ofmass m = 0.24 kg and radius R = 0.16 m) and a thinradial rod (of length L = 2R and also of mass m = 0.24kg). The assembly is upright, but we nudge it so thatit rotates around a horizontal axis in the plane of therod and hoop, through the lower end of the rod.Assuming that the energy given to the assemblythe nudge is negligible, what is the assembly'sangular speed about the rotation axis when it passesthrough the upside-down (inverted) orientation?Number iRodHoop!RotationaxisUnits

According to this law, the total energy of a system remains constant. Mathematically, Ef=Ei…
