roblem 2. A 2 kg block oscillates with an amplitude of 10 cm on a spring of force constant 120 N/m. Notice that these are typical real-world sizes! (a) In which quantum state is the block? Worded another way, find the state of this block by finding the energy, from which you can calculate n. (b) When an object is an excited state - any state that is higher energy than the ground state - it can de-excite by releasing a photon with the exact energy necessary to drop into a lower energy state. What is the minimum energy decrease possible for this block? Express your answer in three ways: (1) in eV, (2) in J, and (3) as a percent of the original energy of the block.
