## Homework Statement

Masses M

_{1}and M

_{2}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 M

_{1}.

## Homework Equations

N/A

## 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 M

_{1}, but I'm not sure that my reasoning really applies here. Could someone please offer some guidance?
