Problem

0.25\,\text{kg}

mass is attached to an ideal spring of force constant

100\,\text{N}\,\text{m}^{-1}

. The system is driven by an external periodic force whose frequency can be varied. Three driving frequencies are available:

1.0\,\text{Hz}

3.0\,\text{Hz}

and

5.0\,\text{Hz}

. Identify which frequency will produce resonance. (Take

\pi^{2}=10
