A person stands on a bathroom (?) scale in a motionless elevator. When the elevator begins to move, the scale briefly reads only 0.75 of the person's regular weight. Calculate the elevator's acceleration, and find the direction of acceleration.
The only thing that I really got is that the scale reading is (3/4)*mg (person's weight). Is there anyone who can tell me how to start?
Thanks.
