Differential equations of motion

  1. Dec 18, 2012 #1
    1. The problem statement, all variables and given/known data

    Write down the differential equations of motion.
    (Step by step if you can)


    2. The attempt at a solution

    x"+(f/m)x'+3(k/m)x=0
    or
    x"+σx'+ω^2x=0
    where σ=f/m and ω=sqrt(3k/m)

    Thanks in advance.
