Question

A particle executes SHM with a period of $8\,s$ and amplitude $4\,cm$ . Its maximum speed in $cm/s$, is

• A. $\pi$
• B. $\frac{\pi }{2}$
• C. $\frac{\pi }{3}$
• D. $\frac{\pi }{4}$

Answer 1

Answer: (A)

$\pi$

Answer 2

For a particle executing SHM
$v_{\max }=A \omega$
$=4 \times \frac{2 \pi}{T}$
$=4 \times \frac{2 \pi}{8}=\pi cm s ^{-1}$
