A 64kg person is standing on a scale in an elevator. the elevator is rising at a constant velocity but then begins to slow, with an acceleration of 0.59m/s^2. What is the sign of the acceleration? What is the reading on the scale while the elevator is accelerating.

fg +fps = ma
where fg is the force due to gravity
fps is the force due to the person on the scale
ma is the submission of the forces of Fy
rearrange the formula to find Fps.
