Two different simple harmonic oscillators have the same natural frequency (f=9.50 Hz) when they are on the surface of the Earth. The first oscillator is a vertical spring and mass, the second is a pendulum. If both systems are moved to the surface of the moon (g=1.67 m/s2), what is the new frequency of the pendulum?
Calculate the new frequency of the vertical spring and mass.
