Practice covered

  1. For a mass oscillating on a spring, what condition must be satisfied for the motion to be simple harmonic?
  2. A 0.5 kg mass oscillates on a spring with spring constant k = 80 N/m. Calculate the period of oscillation (in seconds).
  3. For a mass oscillating on a horizontal spring with amplitude A, where does maximum kinetic energy occur?
  4. A 2.0 kg mass oscillates on a spring with spring constant k = 200 N/m and amplitude 0.15 m. Calculate the maximum speed (in m/s).
  5. A harmonic oscillator has total mechanical energy E. At what displacement from equilibrium does the kinetic energy equal the potential energy?
  6. A 0.8 kg mass on a spring with k = 50 N/m oscillates with amplitude 0.2 m. Find the speed (in m/s) when the displacement is 0.1 m.
