What is the frequency of the simple harmonic motion?

A 2.00 kg mass is connected to a spring with a spring constant of 730 N/m. The displacement is given by the expression x(t)=0.003 cos (omega t). What is the frequency of the simple harmonic motion?What is the frequency of the simple harmonic motion?The natural frequency for a simple spring/mass system is the square root of k/m, where k is the spring constant and m is the mass. Therefore it's sqrt(730/2), or 19.1 rad/s. Hope that helps! If you have any other questions let me know.
