[QUOTE="Simon Bridge, post: 4518532, member: 367532"] I cannot tell how you've done it because I don't know your labelling. However, you appear to be trying to do the problem all in one go. This is not the "correct" approach. You should be drawing a free-body diagram for each mass, apply ƩF=ma to each one (using appropriate choice of + or - signs to show direction), and then solve the system of simultaneous equations. If you do that, questions about what cancels what will resolve themselves. If you know how long the string between masses is, you will have a time-dependent solution - otherwise you should state "as long as m1 and m2 remain on the table" or something like that. [/QUOTE]
