Fletcher's Trolley (Hanging Mass Problem)

[QUOTE="Mike_Stokes, post: 4710484, member: 507412"] [h2]Homework Statement [/h2] A 1.20kg object is placed on a smoothe level table and is attached to a hanging mass using a light string over frictionless pulley in a Fletcher's trolley arrangement. The 1.20kg object accelerates along the table at 2.31m/s^2 while the hanging object accelerates down at the same rate. Determine the a. Mass of the hanging object b. tension in the string [h2]The Attempt at a Solution[/h2] I drew 2 FBDs with the forces acting on each individual mass. We know that Fapp = Fg2 = T What I can't figure out is a formula that rearranges the variables to find m2 For example, I know that a = F/∑m But we don't know what ∑m is. We could relate Fapp to Fg2, but to do that we'd need to know m2 We can relate T to Fapp or Fg2, but we'd need to know m2... You can see my dilemma. I've tried a good 10 different formulas, and now I'm just spitballing. I have no idea how I am supposed to create a formula that tells us m2 without knowing F Please help. [/QUOTE]
