A person stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.61 of the person's regular weight. Calculate the acceleration of the elevator, and find the direction of acceleration.
_______ m/s2
Also which is the direction?
Not enough information to decide
Downwards
Upwards
:confused:

here you need to solve:

1-0.61 = \frac{a}{g}

solve for a.

Which direction would cause someone to be lighter?
