Problem

A spring stretches by

4.0\,\text{cm}

when a

2.0\,\text{kg}

mass is hung from it and is in equilibrium. Find the natural angular frequency of small vertical oscillations of the mass (take

g = 9.8\,\text{m\,s}^{-2}

). a)

9.8\,\text{rad\,s}^{-1}

7.85\,\text{rad\,s}^{-1}

15.7\,\text{rad\,s}^{-1}

31.4\,\text{rad\,s}^{-1}
