Homework Statement

A simple system of mass

Relevant Equations

mainly newtons second law

hey there,

I am confusing what is the right answer to this system of mass, I solved it a couple of time and I got different answers. can you help me with that?
I need to find the expression of the acceleration of the 2 masses.

thanks a lot,Adam.

on the left middle; if the system was stretch all the way. it will be easier to find the length equation, thanks a lot/

I see you somehow got that a₁=a₂. That is incorrect.

Consider that the rope attached to M2 is of constant length. That places a constraint on the relationship between a1 and a2.
