Physics - please help me..
A 1.35 kg mass is suspended from a spring with a spring constant of 189.0 N/m. The spring is attached to a rod which oscillates vertically at a frequency f. For what value of the frequency f will the system resonate?

The frequency at which a system will resonate is known as the resonant frequency and it is related to the mass and spring constant of the system. The resonant frequency of the system given is calculated using the equation f = (1/2π)√(k/m), where k is the spring constant and m is the mass. In this case, the resonant frequency of the system is f = (1/2π)√((189.0 N/m)/(1.35 kg)) = 7.91 Hz. Thus, the system will resonate at a frequency of 7.91 Hz.
