Finding tensions and acceleration in a three-bag pulley system

[nikohnik]

Homework Statement

how to calculate acceleration and tenstion if i only know mass of bags and mass of weight hanger + slotted weights?

I have mass of 3 bags (A=0.037kg, B=0.08kg, C=0.074kg) and Mass of weight hanger + slotted weights (0.21kg) and need to get T1 and acceleration on bag A, T1, T2 and acceleration on bag B and T1, T2, T3 and acceleration on bag C.

Homework Equations

F = ma
T1 - Tabc = (Mabc)a
T2= ?
T3= ?
T2- Fbc = (Mbc)a
T3 - Fc = (Mc)a

The Attempt at a Solution

Does the tension equals the weight?
and is weight = mass * acceleration of gravity (9.8 m/sec^2)??

How is the pulley configured? Can you give the complete question, along with a diagram?
