The string constrains the rotational and translational motion of the cylinder. What is the relationship between the angular rotation rate ωω and vv, the velocity of the center of mass of the cylinder? Remember that upward motion corresponds to positive linear velocity, and counterclockwise rotation corresponds to positive angular velocity. Express ωω in terms of vv and other given quantities
