Answer:
It will remain same i.e. 4.0 Hz
Step-by-step explanation:
In a mass-and-spring system, the frequency depends upon the mass (m) and the spring constant (k).
![f=(1)/(2\pi)\sqrt{(k)/(m)}](https://img.qammunity.org/2020/formulas/physics/high-school/fyxvj0m61xu08vsik6jdsm9h0mj82vp81j.png)
Since, the frequency does not depend on the initial displacement of the mass, the frequency would remain the same i.e. 4.0 Hz.
