A mass of 0.5 kg is attached to a spring with spring constant 50 N/m. What is the angular frequency of oscillation?

Correct answer: B. 10 rad/s

  • A. 5 rad/s
  • B. 10 rad/s
  • C. 15 rad/s
  • D. 20 rad/s

Explanation

Angular frequency ω = √(k / m) = √(50 / 0.5) = √100 = 10 rad/s.

About Simple Harmonic Motion

Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
