Vedclass · Answer

(A) The displacement of the bob in simple harmonic motion is given by $x = A \sin(\frac{2\pi}{T}t)$.In one complete oscillation (time $T$),the bob travels from the mean position to the extreme position $A$,back to the mean position,to the other extreme position $-A$,and returns to the mean position.The total distance covered in one time period $T$ is $A + A + A + A = 4A$.The average speed is defined as the total distance divided by the total time.Average speed $= \frac{	ext{Total distance}}{	ext{Total time}} = \frac{4A}{T}$.
