Problem

A mass of 1 kg1\,\text{kg} is attached to a light spring of force constant 100 N m−1100\,\text{N}\,\text{m}^{-1}. The system has negligible damping and is subjected to a small periodic driving force. At which driving angular frequency will the steady-state amplitude be maximum? (a) 15 rad s−115\,\text{rad s}^{-1} (b) 5 rad s−15\,\text{rad s}^{-1} (c) 10 rad s−110\,\text{rad s}^{-1} (d) 7.1 rad s−17.1\,\text{rad s}^{-1}
