Which of the following choices is the correct formula for the period of oscillation of a mass-spring system?
where:
• T is the period, or time for one full cycle, of oscillation for the mass-spring system
• k is the elastic constant of the spring used in the mass-spring system
• m is the mass of oscillator
$T = 2\pi \sqrt{\frac{1}{km}}$
$T = 2\pi \sqrt{mk}$
$T = 2\pi \sqrt{\frac{m}{k}}$
$T = 2\pi \sqrt{\frac{k}{m}}$
