Homework Statement
A mass m_1 = 4.1 kg rests on a frictionless table and connected by a massless pulley to another mass m_2 = 3 kg, which hangs freely from the string. When released, the hanging mass falls a distance d=0.83m.
How much work is done by tension on m_1?
Homework Equations

[tex]w=Fx[/tex]
The Attempt at a Solution
[/B]
I began with w=Fx. I re-wrote it as
[tex]w=max[/tex]
because F=ma.
But from here I'm stuck. I can't find acceleration, and I'm pretty sure it has something to do with gravity, but not completely. I feel that I'm pretty close but I just can't get that last part.
