A) \[a\omega \cos \theta \]
B) \[a\omega \]
C) \[a\omega \sin \theta \]
D) none of these
Correct Answer: B
Solution :
Given equation is \[x=a\cos (\omega t-\theta )\] So, velocity \[\left| \frac{dx}{dt} \right|=a\,\omega \,\,\sin \,(\omega t-\theta )\] At \[(\omega t-\theta )=90{}^\circ ,\] the velocity will be maximum, therefore the maximum velocity is \[v=a\omega \]You need to login to perform this action.
