3.33. The following data are given for a damped single degree of freedom mass-spring system: mass m =6 kg, damping coefficientc=25 N-s/m, and stiffness coefficient k = 5.5 x 10 N/m. The mass is subjected to a velocity- %3! dependent force. The mass has zero initial displacement and initial velocity of 1 m/s. Determine the displacement and velocity of the mass after 0.1s in the following two cases of the forcing function F (a) F = 50i N; (b) F = 400i N.

3.33. The following data are given for a damped single degree of freedom
mass-spring system: mass m=6 kg, damping coefficient c= 25 N · s/m, and
stiffness coefficient k = 5.5 x 10° N/m. The mass is subjected to a velocity-
dependent force. The mass has zero initial displacement and initial velocity
of 1 m/s. Determine the displacement and velocity of the mass after 0.1s in
the following two cases of the forcing function F
(a) F = 50x N;
(b) F = 400x N.
