Question

http://gyazo.com/bb3d7456192c23d8f7bab4af839a03ee help explain this? I GIVE MEDAL

Answer 1

This is physics... isn't it?

Answer 2

I can help with physics but it has to be in the right group in order for me to help ._.;

Answer 3

just help me dang

Answer 4

what formulaic equations have you learned

Answer 5

pre-warning, i lag a lot so i'm sorry if i take like 30 minutes to respond

Answer 6

only thing i know is vectors i just started collage and i need to get this done

Answer 7

*lags*

Answer 8

ok brb. i'm gonna restart this thing and see if i can get this site to work faster so i can help you.

Answer 9

ok

Answer 10

back.
if i still take a long time to answer i'm sorry ; o;

Answer 11

alright

Answer 12

ok i need to review the equations i am rusty
but first the variables:
m1, m2, [theta]1, [theta]2

Answer 13

ok so friction = 0
we have a "perfect" situation where there is no friction and the wire connecting the boxes has no mass that contributes to the equation...

Answer 14

sorry lagged out
i cannot do this problem and expect a correct answer so i will ask the experts

Answer 15

ok

Answer 16

Do you know how to draw a free-body diagram?

Answer 17

Listen to this guy, I have no idea what I'm doing anymore.
*falls flat on face* x_x

Answer 18

ok im listtening

Answer 19

He is asking if you know how to draw a free-body diagram, @RichHomie.

Answer 20

You know what.

Look at these two pics and tell me if there's anything you don't get.

Answer 21

i know how to just need to know how to solve dis

Answer 22

Okay.

Answer 23

Well, the links I last posted do tell you how to "do" the problem... minus the friction part.

Answer 24

so... can you draw the diagram for us then? since it asks you to do that? (too lazy for proper capitalization)

Answer 25

Drawing free-body diagrams are usually a good first step to tackle mechanics problems.

Answer 26

how to draw a diagram?

Answer 27

Answer 28

Are you still confused?

Answer 29

yea alittle

Answer 30

Did you look at the picture...?
I will find another one if it's too confusing...

Answer 31

okay

Answer 32

Okay, I will try to explain as best I can.
In regards to m1's FBD (free-body diagram), the weight and resisting force must always come DOWN out the BOTTOM of the mass and UP out of the TOP of the mass, respectively
But we need Wx to find the direction and force the mass is being pulled in:

Answer 33

Oh, and F = ma, which leads you to the acceleration formula: a=(F/m)

Answer 34

The equations have friction components, but we do not use friction here, so the above formula will suffice.

Answer 35

listening

Answer 36

We have mass, m1.
So now the formula would be\[a=\frac{F}{m_{1}}\]

Answer 37

For force:
first find Wx:
