(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object of mass on a frictionless horizontal table is connected to an object of mass m_{2}through a very light pulley P_{1}and a light fixed pulley P_{2}. (a) If a_{1}and a_{2}are the accelerations of m_{1}and m_{2}, respectively, what is the relation between these accelerations? Express (b) the tensions in the strings and (c) the accelerations a_{1}and a_{2}in terms of the masses m_{1}and m_{2}, and g.

2. Relevant equations

3. The attempt at a solution

I'm trying to setup the equations correctly. I know I need 2 equations for each object. Right?

Assuming positive direction is down:

[tex]\sum Fy = m_{2}g - T = ma_{2}[/tex]

[tex]\sum Fx = T = ma_{1}[/tex]
