| Sep 19, 2020 at 13:27 | comment | added | David White | You may be partly missing the point. Whenever the problem statement uses a massless string, massless and frictionless pulley, etc., that component is not part of the mathematical model that is used to solve the problem, and the physics of that component can be ignored. This simplifies the problem and makes the problem solution somewhat easier to obtain. | |
