Physics - SHM Question with Solution | TestHub

Given, $\mathrm{m}=0.5\mathrm{kg}.\omega =5\mathrm{rad}/\mathrm{s},\mathrm{x}=10^{-2}\mathrm{m}$,$\mathrm{A}=5\times 10^{-2}\mathrm{m}$ $\because$ Potential energy, $\mathrm{U}=\frac{1}{2}\mathrm{m}{\omega }^2{\mathrm{x}}^2$ or $\mathrm{U}=\frac{1}{2}\times 0.5\times (5{)}^2\times {\left(10^{-2}\right)}^2$ $=\frac{25}{4}\times 10^{-4}\mathrm{J}=6.25\times 10^{-4}\mathrm{J}$ $\because$ Kinetic energy, $\mathrm{K}=\frac{1}{2}\mathrm{m}{\omega }^2\left({\mathrm{A}}^2-{\mathrm{x}}^2\right)$ or $\mathrm{K}=\frac{1}{2}\times 0.5\times (5{)}^2(25-1)\times 10^{-4}$ $=150\times 10^{-4}\mathrm{J}$
