Question

Two masses are connected by springs and slide along a frictionless horizontal track.

Their motion is governed by the second-order system
h1'' = -4h1 - 6(h1 - h2),       h1'' = -6(h2 - h1) - 4h2

where h1 and h2 are the horizontal displacements of the masses from their respective equilibrium positions.

 

(a)Recast this system as a first-order system in the form x' = Ax where

(b)Show that A has the eigenpairs

(c)Give a fundamental set of real solutions for the system x'= Ax.
