Consider the mass-spring and damping system as shown in the figure. A harmonic force F = F0sin ωt acts upon the 11-kg mass. The spring constant is 7093 N/m and the damping coefficient is 252 N.s/m. There is no friction between the small rollers and the horizontal surface. Let F0  =923 N and ω = 117 rad/s. Calculate the period (in seconds) of the steady state vibrations. a) There is no frequency of free vibration, because there is damping. b) 0.2772 c) 0.1301 d) 0.2474 e) 0.0537
