Step 2

Here ω is the angular frequency of oscillation of the particle; x is the displacement of the particle from the mean position.

According to the above expression the acceleration of the particle undergoing a simple harmonic motion is directly proportional to its displacement x from the mean position.

Therefore under maximum displacement from the mean position, the particle will possess maximum acceleration.

Step 3

Let the maximum displacement of the particle executing S.H.M be denoted as xo.

Then a...
