For the system illustrated, neglect the inertia of the pulleys. Help KB MB ACB mc www. (a) Select coordinates, draw the free-body diagrams, state the kinematic constraint equation(s), and derive the equation of motion in terms of the motion of Mas B. (b) Remove the damper and use conservation of energy to derive the equation of motion. (c) From the results of part(a), determine the undamped natural frequency and the damping factor for the system.
