Which one of the following statements is true for the speed

v

and the acceleration

a

of particle executing simple harmonic motion?

Options

AWhen $v$ is maximum, $a$ is maximum
BValue of $a$ is zero, whatever may be value of $v$
CWhen $v$ is zero, $a$ is zero
DWhen $v$ is maximum $a$ is zero

Correct answer

D. When $v$ is maximum $a$ is zero

Step-by-step solution

In SHM

\text{Velocity }=A \omega \sin

\left(\omega t+\frac{\pi}{2}\right)

Acceleration

= A \omega^2 \sin (\omega t+\pi)

This shows that

V

is max then

a=0
