4.11. A damped single degree of freedom mass-spring system is excited at
resonance by a harmonic forcing function which has an amplitude of 40 N.
The system has mass m of 3 kg, a stiffness coefficient k of 2700 N/m, and
a damping coefficient c of 20 N · s/m. If the initial conditions are such
that xo = 5 cm, and to = 0, determine the displacement, velocity, and
acceleration of the mass after t = 0.2 s.
