Answer:
Both have the magnitude of 0.23g, or 2.264 m/s2
Explanation:
So the scale would read 160lb when the elevator accelerates upward and 100lb when the elevator accelerate downward
As 160 / 130 = 1.23, you are experiencing 1.23 g when accelerate upwards. The magnitude of the acceleration upward would be 1.23g - g = 0.23 g, or 9.81*0.23 = 2.264 m/s2.
Similarly, 100 / 130 = 0.77, you are experiencing 0.77 g when accelerate downwards. The magnitude of the acceleration downward would be g - 0.77g = 0.23 g, or 9.81*0.23 = 2.264 m/s2.
