1. The problem statement, all variables and given/known data
In the figure, block 1 of mass m1 = 1.8 kg and block 2 of mass m2 = 1.4 kg are connected by a string of negligible mass. Block 2 is pushed by force Upper F Overscript right-arrow EndScripts of magnitude 18 N and angle θ = 34°. The coefficient of kinetic friction between each block and the horizontal surface is 0.16. What is the tension in the string?

2. Relevant equations
FBD

3. The attempt at a solution

This is my FBD(Is this right?)

I want to do it step by step..
my first thoughts it will be
T1-f=0 -> T1=f (block m1) but I don't know if this right can someone guide me to this question

Thank you and God bless!

Why don't you start with the equations. I prefer doing physics with actual math.

So far so good...sine and cosine for the right!

Okayyy but I got used to using FBD then proceed to do equations. But my problem is I don't know if my FBD is right
