Calculating change in linear position

Click For Summary
The discussion focuses on calculating the change in linear position of a bar with a mass that shifts as the bar rotates around its center of mass. The bar is 1 meter long, has negligible mass, and is subjected to an angular velocity of π rad/s, with a 1 kg mass moving along it. Participants clarify that without external forces, the bar will continue to rotate in the same direction as the center of mass shifts, and the conservation of momentum applies. The complexity arises from the need to derive equations that describe the system's behavior, particularly how the linear position of the bar's center changes as the mass moves. Overall, the conversation emphasizes the importance of understanding the dynamics of the system to accurately model its motion.

I was just hoping to verify that my understanding of the conservation of angular momentum does apply to this situation. I seem to have gotten that verification. I appreciate all of the help, and I am sorry for the amount of time it took me to adequately explain the problem.

Thank you to everyone who has provided assistance.

An object that has no mass will not contribute, in any way, to the linear or angular momentum.
