Kleppner and Kolenkow - Pulleys

• jgens
In summary, the problem involves two masses connected by a system of strings and pulleys, with the task of finding the acceleration of one of the masses. The solution involves taking into account the masslessness and frictionlessness of the pulleys and using the tensions in the strings to solve for the acceleration. There is a discussion about the approach to the problem and the possibility of the reasoning not applying in this specific situation, with a request for guidance.

Homework Statement

Masses M1 and M2 are connected to a system of strings and pulleys as shown. The strings are massless and inextensible, and the pulleys are massless and frictionless. Find the acceleration of M1.

The Attempt at a Solution

I've reasoned that since the pulley is massless, the net force acting on it must be zero (otherwise the acceleration would be infinitely large). I could then use the tensions in the strings to arrive at an answer for the acceleration of M1, but I'm not sure that my reasoning really applies here. Could someone please offer some guidance?

Hi, did you ever get a solution or an approach to this problem? I am also working on the same one right now and am stuck on it...
