1. The problem statement, all variables and given/known data In the figure (attached), find an expression for the acceleration of m_1 (assume that the table is frictionless). 2. Relevant equations Fnet = (m)(a) 3. The attempt at a solution So I am assuming that the Fnet for the box m1 is T, which would be related to the weight of the pulley/box m2. Determining the value of T for box m1 is where I am having difficulty. At first I assumed that Fnet box 1 = (m2)(g), but since there are two ropes on the pulley m1, I thought that Fnet box 1 = (m2)(g)/2. Both of these are incorrect when plugged back to find a: a = Fnet/m1. Also, should the mass for finding the acceleration be just m1, or should I be adding m2 to that as well? Thanks!
