In Exercises 21-28, consider harmonic oscillators with mass m, spring constant k, and
damping coefficient b. (The values of these parameters match up with those in Exer-
cises 13-20). For the values specified,
(a) find the general solution of the second-order equation that models the motion of
the oscillator;
(b) find the particular solution for the given initial condition; and
(c) using the equations for the solution of the initial-value problem, sketch the y(t)-
and v(t)-graphs. Compare these graphs to your sketches for the corresponding ex-
ercise from Exercises 13-20.
