Homework Statement
A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.71 of the person's regular weight. Calculate the magnitude of the acceleration of the elevator.
Homework Equations
FN=mg+ma
The Attempt at a Solution
With the way the problem is worded, I'm assuming that the elevator is going down, which could mean that the equation should be FN=mg-ma? Other than assuming that I really have no idea how to start this problem.
