Topic	Why does AP Physics C have to be so hard
Apocalyptic 09/09/17 9:41:39 PM #9:	Doe posted... Okay so according to diagrams the equation for the first box should be F(worker) - F(box2) = ma Or, 3 - F(box2) = 4.2a Then the second box should be F(box1) = ma, Or, 3 = 1.6a? So since a is shared, a=1.875 and if you plug that back into the original equation then F(box2) = -4.875 Except apparently that is incorrect, a=0.54 and I dont know what i fucked up Yeah, I took the Force(3N) and divided that by the combined masses to get an acceleration of 0.54. If I'm wrong, then I do not deserve to be a physics major and I'll drop out immediately. --- ... <cite>Apocalyptic posted [p:886324870] in Why does A...
