1. The problem statement, all variables and given/known data 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? 2. Relevant equations [tex]v^2 = v_0^2 + 2a(x-x_0)[/tex] [tex]w=Fx[/tex] 3. The attempt at a solution 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.
