6) ring of mass, has the a mass (m= 2 kg) and radius (R=0.4 m), and is initially given an angular velocity (0) =50 radians/sec.) about a horizontal axis. It is then gently placed on a nearly smooth horizontal surface, with a coef of friction of yo(= 20). a) Calculate the linear acceleration that the object experiences. (Be sure to draw all the forces on the diagram below! b) Calculate the angular velocity,c* when pure rolling sets in as a fraction of ow. Then calculate the numerical value, I want to see all he results clearly derived, with neat diagrams drawn and with vectors shown.) Express this angular velocity as a fraction of the initial angular velocity. c) How far will the ring have traveled before the sliding stops and pure rolling sets in? Do this by recognizing that the initial velocity is zero and the final velocity is v* = R c.* BONUS: Derive was a fraction of Cousing the conservation of angular momentum. Wo
