i know this and i know what theta is and i know how to draw an FBD diagram! lol i did take calc and I am enrolled in grade 12 physics:) thanks a lot once again! gud night!<3

this is the original question example 5 i get how to get the acceleration, but what's the difference between part a,b,c opps: forgot the link: people.uncw.edu/ganl/phy201 go to chapter 6, example 5:)

ok...you lost me but i think i got it so wutever lol thanks again! but please, just one more question could you look at this one? https://www.physicsforums.com/showthread.php?t=414563

oh yeh sry but yeh 1:the 2kg dangling off the left of table, 2: the 4kg, main one on the table 3: the 4kg, dangling off the right of the table

yup! so it's right then? thank you SO much...could you just answer one more question for me, really quickly, i just need to clear up something

OMG I GOT IT! ok: Ft(from 1)=ma+fg(of 1) Ft(from 3)=fg(of 3)-ma Ff(of 2)=Ft3-Ft1-ma plllllzzz tell me I am right! lol i hope you understood what i wrote

ohhh ok i get itt so then the net force of that block is equal to ma, and the net force is equal to only the force of friction? because the tensions cancel each other out? but that can't be right...the answer is too easy that way...

oh wow i never knew there was a tension equation... i do have a free body diagram...and so if i have the tension(and they are equal on either side of the block, right?) and my only left unknown is friction...do i just say Ff+T=ma? and then if they are equal on either side...dont they cancel??

btw thanks for taking the time to help me out, much appreciated!:)

how is tension known? and from the left is the tension from the left block...the force of gravity and normal force cancel out...

the tension from the 2kg block dangling off the pulley to the left?

im guessing towards the right...with the block with the most mass?

Homework Statement Body B in the figure weighs 102N and Body A weighs 32N, The coefficients of friction between B and the incline are Ms=0.56 and Mk=0.25. Find the acceleration of the system if a) B is initially at rest b) B is moving up the incline c) B is moving down the incline...

Pulley Systems! HELP! Homework Statement The three blocks in the diagram are released from rest and accelerate at the rate of 1.5m/s^2. What is the magnitude of the frictional force on the block that slides horizontally? i don't know why my picture isn't attaching but basically the image...
