प्रश्न
A particle executes simple harmonic motion. If you are told that its velocity at this instant is zero, can you say what is its displacement? If you are told that its velocity at this instant is maximum, can you say what is its displacement?

उत्तर
No, we cannot say anything from the given information. To determine the displacement of the particle using its velocity at any instant, its mean position has to be known.
