I need a lot of help. :(

My assignment is attached. 7 Questions. I got number one, that's it. It's due on Friday.

Please someone help me with this. I need to understand it.

Help me out in part is fine. I don't have questions 2-7 done.

Thanks

As per PF guidelines, you must show your attempt at the solutions before we can provide you with any help.

Fair enough.

OK for 7.

I set up free body diagrams.

FBD of mass 1 has
- force of friction = 9.8 N pulling it left
- Normal force upwards
- Fg downwards
- tension pulling it right

FBD of mass 2
- friction directed upwards at 35 degrees
- tension also directed upwards at 35 degrees
- Fg perpendicular to the surface (not perpendicular to teh slope)
- normal force perpendicular to slope

X Direction for mass 1
Ftension-Ffriction=ma
Ft=9.8+ma

y Direction for mass 1
Fnormal-Fgravity=0
therefore Fn=Fg

Now I don't know what to do
