Hey ppl, sorry I was just wondering if anyone knew how to do the question i posted earlier(TWO BLOCKS AND TWO PULLEYS), as I have to submit it and cannot figure it out still!?

Thanks...

 oh sorry tiger, its okay i had to submit it, thx for your time...i cant get the pic up for some reason.. Attached Thumbnails
 never mind must have been my browser
 well how did you do the first part? it looks right to me. you did: $$\sum{F} = ma$$ always always ALWAYS start with this over and over again (or at least try to strat with this). The right hand side will have only ma or 0 thats all it will ever have ( and zero is a particular case of ma--when it is not accelarating, that is, not moving, or constant velocity) The left hand side just sums your forces. So after picking your postitive and negnative on your x and y axis (always do this too) and drew your free body diagram (I hop you did this) you must of did: $$T + T = m_2a_2$$ And then you solved for T Now for the next part do the same thing 1) Draw FBD 2) $$\sum{F} = ma$$ 3) $$T - m_1g = m_1a_1$$ And then solve for $$a_1$$ in terms of everything else they gave you
