Two different simple harmonic oscillators have the same natural frequency (f=7.10 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 vertical spring and mass?
Calculate the new frequency of the pendulum.
