Q.
The graph below shows a particle in simple harmonic motion. From the information shown, find the value of time $t_{1}$ (in$s$).
Oscillations
Solution:
The graph shows the time period of the motion to be $24\, s .$
Therefore the value of $t_{1}$ such $\omega t_{1}=\frac{\pi}{6}$
$\Rightarrow t_{1}=\frac{T}{12}$
