Homework Equations
F = ma is it
The Attempt at a Solution
The problem I had is that it's attached to the floor all of a sudden. Never before have we had Atwood problems like this, and I can't find any online... I drew out the free body diagram but probably screwed up somewhere because of it. I know my answer is wrong.
I had T1-mg = ma1
and T2-Mg=Ma2
***I said if m goes down 1, pulley goes up a 1/2, and M goes up 1/4 (this is where I screwed up I think...)***
And thus a1 = -4a2
T1 - mg = m(-4a2)
And the appropriate work ended me with a solution of 2g/3 (which is wrong I'm 99% sure of).
So I need help knowing what I did wrong in the stars (presumably I think this is my mistake, as I have never done it with a floor and was very lost...)
