Answer:
[tex]f=1.79Hz[/tex]
Explanation:
The period is defined as the time taken by an object to complete a cycle in a simple harmonic motion. As the frequency of the motion increases, the period decreases. Therefore, they are inversely proportional. The frequency does not depend on the mass of the object.
[tex]f=\frac{1}{T}\\f=\frac{1}{0.56 s}\\f=1.79Hz[/tex]
