An object is executing simple harmonic motion with an angular frequency $\omega$ If the maximum velocity is $v_{\max }$ then the maximum acceleration of the object is
  1. $\omega^2 v_{\max }$
  2. $\omega v_{\max }$
  3. $\omega \sqrt{v_{\max }}$
  4. $3 \omega v_{\max }$

Solution

In SHM maximum velocity of object, $ \begin{aligned} v_{\max } & =A \omega \\ \Rightarrow \quad A & =\frac{v_{\max }}{\omega} ...(i)\end{aligned} $ Where, $A$ is amplitude and $\omega$ is angular velocity. $\therefore$ Maximum acceleration of the object performing SHM, $ \begin{aligned} & \alpha_{\max }=\omega^2 A \\ & =\omega^2 \frac{v_{\max }}{\omega} [From Eq. (i)]\\ & =\omega V_{\max } \end{aligned} $
