Problem Details

Consider a man standing on a scale which is placed in an elevator. When the elevator is stationary, the scale reading is his weight W. Find S, the scale reading when the elevator is moving downward with acceleration a = 1/6 g.

1. S = 8/7 W

2. S = 6/5 W

3. S = 5/7 W

4. S = 0 m/s2

5. S = 7/6 W

6. S = 4/3 W

7. S = 7/5 W

8. S = 5/6 W

9. S = 6/7 W

10. S = 2/3 W
