Hi haruspex. I was referring to the linear acceleration and the linear (center of mass) velocity.haruspex said:

SUMMARY
The discussion centers on the mechanics of a yo-yo rolling without slipping, specifically analyzing the forces and torques involved when a force is applied to the string. Participants clarify that when the yo-yo is pulled, it will slide to the right while rolling clockwise if friction is sufficient to prevent slipping. The center of mass (CM) velocity is directed to the right, countering the backward rolling motion caused by the string tension. The final equation derived is F = (3μmg)/(1 + 2b/R), illustrating the relationship between applied force, friction, and motion.
