## Homework Statement

Given m_1 on an Atwood's Machine, what is the mass of m_2?## Homework Equations

[itex]a_{net1} = \frac{m_{1}-m_{2}}{m_{1}+m_{2}}g[/itex]

## The Attempt at a Solution

[itex]a_{net1} = \frac{m_{1}-x}{m_{1}+x}g[/itex][itex] \frac{a}{g} = \frac { m_{1} - x } { m_{1}+x }[/itex]

[itex] \frac {a}{g}m_{1} + \frac{a}{g}x - m_{1} = -x [/itex]

[itex]x = \frac { \frac{a}{g}(m_{1}) - m_{1} } {- \frac{a}{g} - 1} [/itex]Is this correct?
