Elevator physics problem..

a 55kg person is standing on a typical scale on an elevator.
what is their apparant weight at
-moving up at constant speed
-moving up when a=2m/s^2
-moving down when a=4m/s^2

having problems knowing what equation to use..? thanks for help

F=MA + MG


moving up at constant speed at a constant speed there no force the apparent weight would be

F=Mg

moving up when a=2m/s^2

F=MA + Mg

F=M(2) + Mg


moving down when a=4m/s^2

F=MA + Mg

F =M(-4) + Mg
