Homework Statement
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.
Homework Equations
[tex]F(t) = F_{0}cos \omega t[/tex] (t > 0)
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?
