Question

The displacement of a particle in $S.H.M.$ is indicated by equation $y=10sin$ $(20t+\pi /3)$ where $y$ is in metres. The value of maximum velocity of the particle will be :

• A. 100 m/sec.
• B. 150 m/sec.
• C. 200 m/sec.
• D. 400 m/sec.

Answer 1

The correct option is C 200 m/sec.

$y=10sin(20t+\pi /3)$

y = a sin $(wt+\varphi )$

$V_{max}=AW$

$=\left(10\right)\times \left(20\right)$

$=200m/g$

Option (C)
