## Homework Statement

Here is the problem verbatim (values have been slightly changed, also assume a frictionless environment):

"A 4.3 kg block A and 6.0 kg block are connected by a string of negligable mass. Force FA = (15 N) acts on block A; force FB = (24 N) acts on block B. What is the tension in the string? "

The diagram can be found here:

## Homework Equations

F=ma

[tex]\vec{F}[/tex]A = 15 N [tex]\hat{i}[/tex]

[tex]\vec{F}[/tex]B = 24 N [tex]\hat{i}[/tex]

Fn - Fg = 0 (forces on y-axis are balanced)

## The Attempt at a Solution

I'm not exactly looking for an answer, I just need a place to start. What I'm having trouble with is drawing the free-body diagram, and if I am doing that correctly then I need help interpreting the values that I have.

Heres pretty much what I have been able to come up with as a free-body diagram:

I have a feeling that my diagram is missing some vital forces (I believe this problem requires me to apply Newtons Third Law, but I'm unsure how to display that graphically)
