The hoist has a 5-year life and an estimated salvage value of $1,394. Installation costs were $2,841, and freight charges were $852. Carleton uses straight-line depreciation.
Using the Hamiltonian for the harmonic oscillator, or otherwise, show that the expectation value of the kinetic energy is equal to the expectation value of the potential energy and half that of the total energy.
