A) 10 cm, \[\frac{2}{3}s\]
B) 10 cm, \[\frac{3}{2}s\]
C) 5 cm, \[\frac{3}{5}s\]
D) 5 cm, \[\frac{2}{3}s\]
Correct Answer: A
Solution :
\[y=5\left( \sin 3\pi t+\sqrt{3}\cos \pi t \right)cm\] \[\Rightarrow \] \[y=10\,\sin \,(3\pi t+\phi )\] \[\Rightarrow \] \[A=10\text{ }cm\] \[\Rightarrow \] \[T=\frac{2}{3}\sec .\]You need to login to perform this action.
