Velocity of two identical masses over a frictionless pulley

[QUOTE="BiGyElLoWhAt, post: 4885390, member: 496972"] Here's my honest opinion: I honestly can't make sense of your equations. It looks like you're trying to use energy's, which you should be able to do, but I don't know what your equations mean. What is E1? What is E2? what is dE? is dE differential energy, whereas E1 and E2 are total energy? If so, how do you get dE = E1 + E2? I'm assuming mghf is final GPE and mghi is initial GPE, which works, but there's a significant lack of organization IMHO. Also, forces definitely work in this situation as well, as NTW said. [/QUOTE]
