For the simple harmonic motion d = 9cos (pi//2t), what is the maximum displacement from the equilibrium position?

The maximum displacement from the equilibrium position is 9.

Step-by-step explanation:

The given simple harmonic motion is:

Differentiating above equation with respect to t, we get

⇒

Again differentiating the above equation with respect to t, we have

Now,

⇒

⇒

⇒

⇒

Substituting the value of t=0 in d, we get

⇒

⇒

⇒

⇒

Therefore, the maximum displacement from the equilibrium position is d= 9.
