A) 0.7 Hz
B) 1.2 Hz
C) 1.9 Hz
D) 0.1 Hz
Correct Answer: C
Solution :
\[{{\omega }^{2}}A=g\] \[T=\frac{2\pi }{\omega }\] \[\omega =2\pi t\] \[{{\omega }^{2}}(0.07)10\,m/{{s}^{2}}\] \[4{{\pi }^{2}}{{f}^{2}}(0.07)=10\,m/{{s}^{2}}\] \[f=\frac{5}{\sqrt{7}}=Hz=\,\,=1.9\,Hz\]You need to login to perform this action.
