Question 6:(8 points) A 1/8-kg mass is attached to a spring with stiffness 16N/m. The damping constant for the system is 2N-sec/m. If the mass is moved 3/4 to the left of the equilibrium and gives an initial leftward velocity of 2m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod and quasifrequency
