Two different simple harmonic oscillators have the same natural frequency (f=2.60 Hz) when they are on the surface of the Earth. The first oscillator is a pendulum, the second is a vertical spring and mass. 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.
