    Find the acceleration of a block (some sort of double Atwood machine?)

    Turns out the problem really was the sign of convention being inconsistent. I hope I got it right this time. I'm still a little confused with the LaTeX so I'll be using my handwriting for now.

    Find the acceleration of a block (some sort of double Atwood machine?)

    This makes so much more sense, thank you so much. But if I had used the pulley as frame of reference and applied pseudo forces would ## T – m_1 g = m_1 a## and ##m_2 g – T = m_2 a## still be usable?

    Find the acceleration of a block (some sort of double Atwood machine?)

    Sorry to reply twice, but I did the early steps with my teacherand thats what he wrote. I assume that's incorrect?

    I'm a new user! Yay

    I'm a high school student and my teacher signed me up for some kind of olympiad and now I'm learning stuff, but at a pretty slow pace. I study using Halliday's book and sometimes also Morin, but I still think his problems are a little difficult. Anyhow, I'm grateful to have found this website...

    Find the acceleration of a block (some sort of double Atwood machine?)

    I hope the sketch is good enough My attempt: anything with k means it's the pulley's. ak means the pulley's acceleration, xk means the pulley's rope length. So my idea here was to use the constraint a1 = 2ak - a2, find the eq for ak and a2 in terms of a1, group them and find a1, but instead I...

    Working out the accelerations in a double Atwood pulley system

    Is it possible to do if we use m2 as frame of reference?
