Homework Help: 3 body problem in 1D

  1. Aug 19, 2007 #1
    1. The problem statement, all variables and given/known data

    if 3 identical objects with mass m are conneted by springs of spring constant k, moving in 1D. At t=0, the masses are at rest at their equilibrium. position. Mass A is then subjected to an external force.

    A -> B -> C

    Where A, B, C are the masses and -> represents the springs.

    Calculate the motion of mass C.

    2. Relevant equations

    [tex]F(t) = F_{0}cos \omega t[/tex] (t > 0)

    3. The attempt at a solution

    The two body problem is easy to solve. (i.e. For A and B). But, i'm confused on how to incorporate mass C into the motion from A and B. Can anyone give me some tips on how to tackle this?
