Question

What is the equation for a damped oscillator, where k and b are constants and  is  x displacement.

  1. fraction numerator md squared x over denominator dt squared end fraction equals kx plus fraction numerator bd x over denominator dt end fraction equals 0
  2. fraction numerator md squared x over denominator dt squared end fraction XkX equals fraction numerator bd x over denominator dt end fraction
  3. m fraction numerator straight d squared x over denominator dt squared end fraction equals kx plus fraction numerator bd x over denominator dt end fraction
  4. fraction numerator md squared x over denominator dt squared end fraction minus kx equals straight b fraction numerator straight d x over denominator dt end fraction

The correct answer is: fraction numerator md squared x over denominator dt squared end fraction equals kx plus fraction numerator bd x over denominator dt end fraction equals 0
