A 200 gram yo-yo in a shape of cylinder with the radius of 5.00 cm is released from rest, at the height h= 20.0 cm above the table top. As the yo-yo descends, the string wrapped around yo-yo's axis does not slip.
Using the dynamics equation (i.e., Newton's second law and the corresponding law for the rotational motion), determine the downward acceleration and the downward velocity of the center of mass of the yo-yo after it has descended all the way to the table top.
