The amplitude of vibration of a single degree of freedom spring-mass-damper system is observed to reduce to 15 % of its initial value after 5 cycles. Spring stiffness equals (1506) N/m and mass equals (13.5) kg. Determine: The undamped natural frequency; The damped natural frequency; The logarithmic decrement
