# Physics

You stand on a bathroom scale that rests on the floor of an elevator. Standing on the scale compresses internal springs and activates a dial that indicates your weight in newtons. When the elevator is at rest, the scale reads 600 N. Then the elevator begins to move upward with a constant acceleration of 2.00 m/s/s.

Determine the scale reading while the elevator is accelerating.
If you read the scale without realizing that it is accelerating upward what might you think your mass is?

2. I would say the true mass is 60 kg and that's as far as i got

3. mg = 600 N,
m =600/g =600/9.8 = 61.2 kg.
W = ma+mg =61.2(2+9.8) = 722 N,
scale will give 722/9.8 = 73.7 kg.
