If you don't want to save the rotor (they are being replaced) whack evenly front, edges and back.
Keep in mind not too hard so you don't damage the wheel bearings. I have found hitting the face in the lug nut area works well. Also dribble some pentrating oil around them.
Be sure to use a metal hammer. A plastic one is just too gentle.
I have learned that it isn't how hard you whack it, it is how much. All you have to do is to get one microscopic section to break free.
I was told years ago when I was wrenching and ran up against a stubborn rotor to think it will take 500 whacks to get it off. It came off after about 40.
To make it easier in the future, I suggest using a light film of anti-sieze on the mating surfaces. Anti-Sieze because it takes high temperatures well.
