5. The Hamiltonian operator is composed of two parts: Kinetic Energy and Potential Energy a) Determine the following commutators: [x, KEx] = [x, 0 (x)]= b) Determine the following commutators: [, KE]= [ , 0 (x)] = There in both cases V(x) = f(x) with no derivatives. c) Under what circumstances could P. commute with , and why? d) Under what circumstances would i commute with fx and why
