  In Part I of this contribution, a systematic coarse-grained description of
the dynamics of a weakly-bending semiflexible polymer was developed. Here, we
discuss analytical solutions of the established deterministic partial
integro-differential equation for the spatio-temporal relaxation of the
backbone tension. For prototypal experimental situations, such as the sudden
application or release of a strong external pulling force, it is demonstrated
that the tensile dynamics reflects the self-affine conformational fluctuation
spectrum in a variety of intermediate asymptotic power laws. Detailed and
explicit analytical predictions for the tension propagation and relaxation and
corresponding results for common observables, such as the end-to-end distance,
are obtained.
