The figure (attached (5-56))shows a box of mass m2 = 2.60 kg on a frictionless plane inclined at angle θ = 33°. It is connected by a cord of negligible mass to a box of mass m1 = 4.00 kg on a horizontal frictionless surface. The pulley is frictionless and massless.

(a) If the magnitude of horizontal force is 2.3 N, what is the tension in the connecting cord?

(b) What is the largest value the magnitude of may have without the cord becoming slack?

2. Relevant equations

Newton's Laws

3. The attempt at a solution

Unfortunately this is the part of physics where I became lost in high school and im having a difficult time putting everything together.

So the first thing that I did was set up axes for each. I set m1 as a normal x and y coordinate system, and m2 with a tilted x-y coordinate system (attached FBD).

So first I attempted to find w2 because that should help me find tension.

[tex]\sum F_x=m_2*a_x[/tex]

[tex]T-w_{x2}=m_2*a_x[/tex] \\w in the x direction of mass 2

[tex]w_{x2}=-2.6*sin(33)[/tex]

I should use this to solve for [tex]a_x[/tex]?

moving on to m1

[tex]\sum F_x=m_1*a_x[/tex]

[tex]T+F=m_1*a_x[/tex]

Do I plug in for a_x because if I do, then I have a T on both sides, in a place that wouldnt be easy to solve?

And even where I am at I believe I have made a huge mistake. I am having problems understanding this. Please help me.
