An object of mass $\displaystyle 0.5$ kg is executing simple harmonic motion. Its amplitude is $\displaystyle 5$ cm and time period (T) is $\displaystyle 0.2$ s . What will be the potential energy of the object at an instant $\displaystyle \mathrm{t}=\frac{\mathrm{T}}{4} \mathrm{~s}$ starting from mean position. Assume that the initial phase of the oscillation is zero.
Official answer
(3)
0.$\displaystyle 62$ J
