A) \[\frac{\pi }{4\omega }\]
B) \[\frac{\pi }{2\omega }\]
C) \[\frac{\pi }{\omega }\]
D) \[\frac{2\pi }{\omega }\]
Correct Answer: A
Solution :
\[x=A\cos \left( \omega t+\frac{\pi }{4} \right)\] and \[v=\frac{dx}{dt}=-A\omega \sin \left( \omega \,t+\frac{\pi }{4} \right)\] For maximum speed,You need to login to perform this action.
