A body of mass \(10.0 \mathrm{~kg}\) oscillates with an amplitude \(10 \mathrm{~m}\) when it is hung on a spring of stiffness \(120 \mathrm{~N} / \mathrm{m}\). Calculate the period at that point.
A. \(1.20\) secs B. \(1.02 \operatorname{secs}\) C. \(1.7 \mathrm{I} \operatorname{secs}\) D. \(1.81 \mathrm{secs}\)
