## Homework Statement

A 100kg man stands on a scale in an elevator moving downward. If the elevator decelerates at ##2 m/s^2##, determine the scale reading (in kg).

## Homework Equations

##N = -WT = -Mg##

## The Attempt at a Solution

##-WT = -100(g)##

##-WT = -100(-10)##

##-WT = 1000##

##Ma = 100(-2)##

##Ma = -200##

##N = -WT + Ma##

##N = 1000 - 200##

##N = 800##

##kg = N/g##

##kg = 800/10##

##kg = 80##

Could any of us please check if this seems correct? Would there be any other possible ways of achieving the answer?
