## Homework Statement

An 80.0 kg man is standing on a scale calibrated in Newtons inside an elevator. Determine the apparent weight of the man as shown by the scale as the elevator is

a. stationary. [ans.785 N]

b. accelerating downwards at a rate of 1.10 m/s^2. [ans. 697 N]

c. accelerating upwards at a rate of 1.10 m/s^2. [ans. 873 N]

d. moving upwards at a constant velocity. [ans. 785 N]

## Homework Equations

Fnet= ma

3. The Attempt at a Solution [/B]

For a. I used the equation Fnet=ma and multiplied 80 by 9.81 and got 785 N, but when I tried the same method for b. (80 kg * 1.10 m/s^2) I got 88 N. This is wrong and I can't figure out how to solve it, I now that the apparent weight will decrease since the elevator is going downwards. I feel like the method for solving c. and d. is going to be the same as the method for solving b..
