So the problem I am working on is: In the figure, find an expression for the acceleration of (assume that the table is frictionless). I have attached the figure of reference.(adsbygoogle = window.adsbygoogle || []).push({});

I have so far tried to solve by first looking at m2 to get:

2T-m_2*g=m_2*a so T= (m_2*(a+g))/2

Then by looking at m1 I got:

T=m_1*a so a=(m_2*g)/(2*m_1-m_2)

This is supposidely wrong.

Can anyone see what I did wrong and how to fix it?

Should it be a=(m_2*g)/(2*m_1+m_2) ?
