How do you find the equation of motion for an idealized model?
For this model how do you find the periodic time (time in sec) and the natural frequency (rad/sec)?

Mechnical Vibration Analysis
I have a mass-spring-damper system that is tested to determine the value of the viscous damping coefficient c. Assume k=10lb/ft and m=2 slug. The vibrational amplitude is observed to decrease to 33% of its initial value after two consecutive cycles.
How do I deduce the value of the logarithmic decrement?
How do I deduce the value of the viscous damping factor?
How do I deduce the value of the viscous damping coefficient c?
