• A. motion of a simple pendulum starting from mean position
• B. motion of a simple pendulum starting from extreme position
• C. simple pendulum describing a horizontal circle
• D. none of the above

Answer 1

Answer: (A)

For a simple pendulum, starting from mean position, $x=A\sin \omega t$
$v=\frac{dx}{dt}=\omega A\cos \omega t$
The given graph is a cosine graph
