5) A ring of mass, has the a mass (m 2 kg) and radius (R-0.4 m), and is initially given an angular velocity (A-50 radians/sec.) about a horizontal axis. Then gently placed on a nearly smooth tortzontal surface, with a coef of friction of (-20). a) Calculate the linear acceleration that the object experiences. > Calculate the angular velocity, .*, when pure rolling sets in. [I want to see all he results clearly derived, with neat diagrams drawn and with vectors show Express this angular velocity as a fraction of the initial angular velocity. How far will the ring have traveled before the sliding stops and pure rolling sets in. ? d) Do the calculations all over again, using the conservation of angular momentum.
