This isn't a homework question, I just thought of it but don't know how to model the situation
Given a pulley system like this
http://img101.imageshack.us/img101/2106/pulleys.png
suppose the string is massless and the pulleys are massless and frictionless.
say m2 is greater than m1, each having 2*tension force pulling up, they will have different accelerations since f=ma?
But since the length of the string is conserved, shouldn't they both be moving up at the same speed, hence their acceleration should be the same?
I am very confused. Help please!
