A) 2m
B) 16m
C) 4m
D) 8m
Correct Answer: B
Solution :
[b] \[\omega =VK\text{ }general\text{ }\,\,\,y=a\text{ }sin\text{ }\!\![\!\!\text{ }\omega \,\text{-}\,\text{kx }\!\!]\!\!\text{ }\] \[y=a\,\sin \,\pi \,\left( \frac{t}{2}-\frac{x}{4} \right)\] \[V=\frac{\pi }{2}\times \frac{4}{\pi }=2m/s\] \[d=Vt\] \[d=2\times 8\] \[d=16\,metres\]You need to login to perform this action.
