For the system of New: 3.6.16 (a) Old: 3.6.16 (a), solve
both the given inhomogeneous problem with zero initial
conditions and the homogeneous problem for arbitrary initial
conditions. ``Solve'' means here find and .
Do not try to find and themselves. Assume the
constant is a viscous damping constant, even though it looks
like dry friction.
Now address part (b) of the same question. Hint 1: look at the
form of the partial fraction solution to see the qualitative
response of mass . Hint 2: some of the roots of the denominator
may be hard to identify mathematically. Use the physics instead.
Based on energy considerations, what can you say about the long-term
behavior of the homogeneous equations? So what does that say
about the roots of the denominator for the homogeneous solution?
