## Homework Statement

Two masses are tied together by a string over a massless pulley so that they can both move vertically. Their masses are 1 kg and 3 kg. What is the acceleration of the 1 kg mass?

## Homework Equations

F=ma

W=mg

## The Attempt at a Solution

I have the 3 kg mass's summation of forces as ma-T. (In my free body diagram, the 3kg mass is the one closest to the pulley.)

The 1 kg mass's summation of forces are mg-T.

I'm unsure if my diagram is correct and I don't know where to go from here.
