The figure shows a thin ring of mass `M=1kg` and radius `R=0.4m` spinning about a vertical diameter (take `I=(1)/(2)MR^(2))` A small beam of mass `m=0.2kg` can slide without friction along the ring When the bead is at the top of the ring the angular velocity is `5rad//s` What is the angular velocity when the bead slips halfwat to `theta=45^(@)`?
