The instantaneous displacement of a simple harmonic oscillator is given by

= a\,\,\,\cos \left[ {\omega t + \frac{\pi }{4}} \right]

. Its speed will be maximum at the time

View answer and explanation

Correct option: D

\frac{\pi }{{4\omega }}

Option D (

\frac{\pi }{{4\omega }}

) is correct because the speed is maximum when the displacement is zero, which occurs at

t = \frac{\pi }{{4\omega }}

for the given equation.
