Question

Q. A particle starts its SHM. At a particular instant t = 0, it is at x = A/2. Find the time t taken by the particle to come back to mean position after reaching the extreme position.

Answer 1

Dear Student ,

$$\begin{gathered} Asweknowthat \\ y=A\sin \omega t \\ y=\frac{A\sin 2\mathrm{\pi }}{T}t \\ \frac{A}{2}=A\sin \frac{2\mathrm{\pi t}}{T} \\ t=\frac{T}{12} \end{gathered}$$
