Engineers can determine properties of a structure that is modeled as damped spring oscillator–such as a bridge–by applying a driving force to it. A weakly damped spring oscillator of mass 0.252 kg is driven by a sinusoidal force at the oscillator\'s resonance frequency of 24.3 Hz. The amplitude of the driving force is 0.439 N and the amplitude of the oscillator\'s steady-state motion in response to this driving force is 0.914 m. What is the oscillator\'s damping constant?

you can either derive the equation of motion from 1st principles (Newtons law etc. ) or look it up..damped SHM
