I am replacing my p trap. Do I need to cut this pipe and use an adapter to connect the new trap?

Hey guys I'm trying to replace a leaking p trap. Do I need to cut the pipe pictured here and use an adapter? If so, do I cut it right before the bend?

Why cant you just loosten or remove the nut and pull the arm out of the wall ? I cant see back there but beyond the white washer there should have been a nut

thanks for your reply. I tried to pull the arm out of the wall but it is very well stuck in there. The nut is on the end of the curve in the picture. The nut screws onto the fixture coming out of the wall. Others have suggested that I use a hair dryer to heat up the arm and try to pull it out. I able to twist it counterclockwise with great effort but I was not able to pull it out.

I tried pulling the tubular arm out but I was unable to. It is stuck. Do you have any suggestions on how to pull out a stuck arm? Thank you.
