SUMMARY
The mass on the right side of the chain is calculated as p*(b-x)/2, where p represents the linear mass density and b is the initial length of the chain. As the chain falls a distance of x, the distribution of mass changes, with half of the chain's length contributing to each side. The confusion arises from determining when to use center of mass (CM) versus total mass in such problems. This clarification is crucial for accurately solving dynamics involving hanging chains.
