In Figure Q5, the 17 kg of circular disk is originally rotating with a clockwise angular velocity, w = 49 rad/s at the end of the link BC. Given the kinetic coefficient of friction, µx = 0.25 when the disk is then placed against the wall. (i) Draw the kinetic diagram of all forces exerted on the circular disk. (ii) Calculate the force of link BC. (iii) Calculate the angular acceleration of the circular disk. (iv) Calculate the time required to stop the motion of the circular disk,
