Worked practice questions

Time period of a spring-mass system (spring constant $k$, mass $m$) is:

  1. $T = 2\pi\sqrt{m/k}$
  2. $T = 2\pi\sqrt{k/m}$
  3. $T = 2\pi mk$
  4. $T = 2\pi/(km)$
Show answer and solution

Correct answer: A. $T = 2\pi\sqrt{m/k}$

**Newton's law + Hooke:** $m\ddot x = -kx$ ⇒ $\omega = \sqrt{k/m}$ ⇒ $T = 2\pi/\omega = 2\pi\sqrt{m/k}$. *Note: independent of gravity (works horizontally and vertically — gravity only shifts equilibrium).*
