Question:
A small 3-kg collar C can slide freely on a thin ring of mass 4.5 kg and radius 325 mm. The ring is welded to a short vertical shaft, which can rotate freely in a fixed bearing. Initially the ring has an angular velocity of 35 rad/s and the collar is at the top of the ring (θ = 0) when it is given a slight nudge. Neglecting the effect of friction, determine
(a) The angular velocity of the ring as the collar passes through the position θ =90?,
(b) The corresponding velocity of the collar relative to the ring.
