v=f*wavelength
30m/s=f*(0.35m)
f=85.7 Hz

Answer:

85.7Hz

Explanation:

We know that the wave velocity is given by:

v=f*λ

where:

f is the frequency

λ is the wavelength

rearranging the equation we have:

f=v/λ

[tex]f=\frac{30m/s}{0.35m}\\f=85.7s^{-1}=85.7Hz[/tex]

so the pendulum has a frequency of 85.7Hz
