Displacement versus time curve for a particle executing SHM is shown. Identify the points marked at which

i) velocity of the oscillator is zero

ii) speed of the oscillator is maximum

Answer:

(i) The oscillator’s velocity is zero when the points A, C, E, and G are at their extreme positions.

(ii) The oscillator’s speed is greatest when the points B, D, F, and H are in their mean positions.
