A) \[200\,\,cm/s\]
B) \[100\,\,cm/s\]
C) \[50\,\,cm/s\]
D) \[10\,\,cm/s\]
Correct Answer: A
Solution :
Given equation is \[y=a\sin (0.01x-2t)\] ... (1) The standard equation is \[y=a\sin (kx-\omega t)\] ... (2) Comparing equations (1) and (2), we get \[k=0.01\]and\[\omega =2\] From the formula, velocity is \[v=\frac{\omega }{k}=\frac{2}{0.01}=200\,\,m/s\]You need to login to perform this action.
