Apparent Weight. A physics student weighing 600 N stands on a bathroom scale in an elevator. As the elevator starts moving, the scale reads 420 N .

A )Find the magnitude of the acceleration of the elevator.

B ) Find the direction of the acceleration of the elevator.( up or down )

thanks ,,,

The weight is less, so the elevator is falling.

weightapparent= mg + ma were + is up, g= 9.8m/s^2

solve for a.
