Problem 6: By pressing down with the finger at B, a thin ring having a mass m and radius r 1s given an initial velocity v, and a (clockwise) backspin w, when the tinger 1s released. If the coefficient of kinetic friction between the table and the rings 1s p,. determine the distance the ring travels forward before the back- spinning stops. 1 Tw Ans: s = (v{, (uo'r) ( 0) 2 Hirg
