Answer:
4.06 Hz
Explanation:
For simple harmonic motion, frequency is given by
[tex]f=\frac {1}{2\pi}\times \sqrt{\frac {k}{m}}[/tex] where k is spring constant and m is the mass of the object.
Substituting 0.2 Kg for mass and 130 N/m for k then
[tex]f=\frac {1}{2\pi}\times \sqrt{\frac {130}{0.2}}=4.057670803\\f\approx 4.06 Hz[/tex]
