A) 300
B) \[\frac{3\pi }{6}\]
C) 100
D) \[\frac{\pi }{6}\]
Correct Answer: A
Solution :
Rate of change of displacement is equal to velocity. Given, \[y=3\,\sin \left( 100\,t+\frac{\pi }{6} \right)\] \[\therefore \] \[v=\frac{dy}{dt}=300\,\cos \left( 100\,t+\frac{\pi }{6} \right)\] Value of \[\cos \theta \] lies between -1 to + 1, hence maximum value of velocity is 300 m/s.You need to login to perform this action.
