1. The problem statement, all variables and given/known data I was wondering how to construct the velocity operator 2. Relevant equations P=MV 3. The attempt at a solution Since P=MV, i used the linear momentum operator and divided by M to get V. Is this the right way to construct an operator from linear momentum and position operators? I did something similar to this to construct the hamiltonian and got the hamiltonian operator. I was wondering about this because i wanted to see if linear momentum and velocity commute. I calculated that they do commute, can someone verify this?
