4. (15 points): The 0.5-lb block B shown in Fig. (a) slides along the rotating bar OA. The coef- ficient of kinetic friction between B and OA is μ = 0.2. In the position shown, R = 2 fus, é = 5 rad/s, and = 3 rad/s². For this position, determine R, the acceleration of B relative to bar OA. -R=1.2 ft 0=40⁰ 5 rad/s 0=3 rad/s Draw FBD and MAD, label clearly and solve.
