Problem

During its motion, a

0.40\,\text{kg}

mass in simple harmonic motion has an acceleration of

1.6\,\text{m}\,\text{s}^{-2}

when its displacement is

0.020\,\text{m}

from equilibrium. The force constant

k

of the system is a)

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

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

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

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