A-kg mass is attached to a spring with stiffness 6 N/m. The damping constant for the system is 2 N-sec/m. If the mass is moved m to the left of equilibrium and given an initial rightward velocity of misec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.
