Question:

Consider a macroscopic oscillator, given by a mass of m = 0.1 kg on a spring with spring constant k = 0.4N/m. What is the natural frequency ω of this oscillator? Considering this as a quantum system, what is the spacing of the energy levels? Do you expect that we could observe the energy of the mass on the spring with sufficient precision to determine which quantum state the system is in? Classically, consider extending the spring by moving the mass a distance d = 1 cm from equilibrium, and letting go. Describe the classical motion of the mass. What is the energy of this system? Roughly what excitation number n characterizes quantum states with this energy?
