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