Imagine designing an experiment to determine the mass of an unknown object by attaching it to a spring, setting it in motion, and observing how fast it vibrates. Assume that you know the spring constant k, and that you can ignore the effects of damping. Derive a formula for finding the mass of an object given the spring constant, k, and the oscillating frequency, f0. Explain how you derived your formula.
