The mass of a mass-and-spring system is displaced 10 cm from its equilibrium position and released. A frequency of 4 Hz is observed. What frequency would be observed if the mass had been displaced only 5 cm and then released?
A) 8 Hz
B) 6 Hz
C) 4 Hz
D) 2 Hz

Question

The frequency of a mass-and-spring system is determined by the mass and the stiffness of the spring, not by the amplitude of the displacement. Therefore, halving the displacement does not change the frequency.
