If I had a hamiltonian of the form iA(p + c), where A is a constant matrix, p the momentum operator and c an ordinary constant how do I find the time rate of change of the expectation momentum value?(adsbygoogle = window.adsbygoogle || []).push({});

I've tried using Ehrenfest's theorem but I don't understand whether in [p,H], I should treat p as an operator or as an ordinary number? Could someone please make this clearer to me? Thanks.
