$(8$ pts $)$ A $\backslash (100-\backslash$mathrm$\{$kg$\}\backslash )$ box is on a scale in an elevator that was moving up at a constant speed and is now coming to a stop. If it takes $2\mathrm{.}5$ seconds for the elevator to go from moving at a constant speed of $\backslash (2\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ to being stationary, what does the scale read as the elevator is slowing down? You can assume the acceleration of the elevator is constant during the time it is slowing down.

A$.820$ N

B$.980$ N

C$.1060$ N

D$.900$ N

E$.800$ N
