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\[\upsilon =a\omega \]You need to login to perform this action.
