Answer:
downward
Explanation:
There are two forces acting on the passenger on the elevator:
- The upward normal force, R
- The weight of the passenger, W
Therefore we can write Newton's second law as
![R-W=ma](https://tex.z-dn.net/?f=R-W%3Dma)
where a is the acceleration of the passenger and m its mass. Here we took upward as positive direction, so that R is positive.
The mass of the passenger can also be written as
![m=\frac{W}{g}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7BW%7D%7Bg%7D)
where g = 9.8 m/s^2 is the acceleration of gravity.
So the equation becomes
![R-W=\frac{W}{g}a](https://tex.z-dn.net/?f=R-W%3D%5Cfrac%7BW%7D%7Bg%7Da)
And solving for a, we find the acceleration:
![a=\frac{g}{W}(R-W)=\frac{9.8}{650}(620-650)=-0.45 m/s^2](https://tex.z-dn.net/?f=a%3D%5Cfrac%7Bg%7D%7BW%7D%28R-W%29%3D%5Cfrac%7B9.8%7D%7B650%7D%28620-650%29%3D-0.45%20m%2Fs%5E2)
and the negative sign means the direction is downward.
