A bos of mass m2= 3.5 kg rests on a frictionless horizontal shelf is attached by strings to boxes of masses m1= 1.5 kg and m3= 2.5 kg, which hang freely. Both pulleys are frictionless and massless. The system is initially held at rest. After it is released, find (a) the acceleration of each of the boxes, and (b) the tension in each string.
If you are confused about the graph, imagine the the m2 is in the middle with 2 strings on 2 sides, at 2 ends of the shelf there are 2 pulleys and m1 hangs on the left of the shelf and m3 hangs on the right of the shelf.
The Attempt at a Solution
I tried to get the Tension at rest but it not gonna do anything with the final answer.
