A 105 kg person stands on a scale in an elevator. The scale reads 1500 N.

Is the elevator at rest, moving up or down at a constant velocity, accelerating upward or accelerating downward?

What is the magnitude of the elevators acceleration?

hello

force=mass*acceleration

= 105*9.8

=1029 N

1029 N< 1500 N,so the elevator is accelerating upward

When the elevator was at rest your weight was 1029 N

let the upward acceleration be xNow your weight is 105*(9.8 +x) = 1500

(9.8 +x) =1500/105

x = 14.28 - 9.8

x = 4.49 m/s^2

magnitude of the elevators acceleration = 4.49 m/s^2 upward
