Homework Equations
The Attempt at a Solution
I know the answer is (2m_2_g)/(m_2_+4m_1_)
My problem is I don't know where the 2 and the 4 are coming from. The only thing I can think of is because block 2 is connected to a pulley that is connected to another one you make times m_2_g by two, and because there are 4 objects with tension that makes m_1_a=(T/4), but that doesn't really make sense.
