A3-kg mass is attached to a spring with stiffness 30 N/m. The damping constant for the system is 2

N-sec/m. If the mass is moved 12 m to the left of equilibrium and given an initial leftward velocity of

31

m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod,

and quasifrequency.
