A yo-yo is held by a steady hand and allowed to unwind from rest. The yo-yo has a mass m = 0.10 kg and a moment of inertia of 0.40mr 2 , where r is the radius of the inner spool that the string is wound around. Determine the acceleration of the yo-yo's center of mass and the tension in the string while it falls..
