Question

Which one of the following statements is true for the speed $v$ and the acceleration $a$ of a particle executing simple harmonic motion?\

Professor PC Thomas Classes · Answer

(d) : In SHM\ $v=A \omega \sin (\omega t+\pi / 2)$,\ $a=A \omega^{2} \sin (\omega t+\pi)$. From this we can easily find out that when $v$ is maximum, then $a$ is zero.\
