Extracted text: The spring-damper-mass system shown in Figure Q3(c) is at rest when strict by a hammer with an initial velocity of 0.4 m/s causing the mass to move upwards. Given that the mass m = 2 kg, spring constant k = 128 N/m and coefficient of 0.6 Ns/m. viscous damping c = (i) Determine the damped frequency of the spring-damper-mass system. Base on the given conditions derived in Q3(c)(i) and parameters given above, describe how you would derive the equation of motion of damped-free vibration. (ii)
