Newton's Law of Motion

  1. Sep 1, 2015 #1
    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
