Physics question. most basic question ever

[MikeMike]

A man weighs 0.8 kN. What is his mass in kilograms?

wouldnt this just be .8kN/9.8m/s^2? thus giving you .0816kg????

cuz thats not the right answer.

now im confuzzled.

on the moon? or on pluto?

 

[dighn]

gravity is newton/kg

so it's 800 / 9.8 = some sensible number

 

[mAdMaLuDaWg]

kN = 10^3 N

kg is a special case in the metric system :thumbsdown:

in english again?

all i have to go by is what i typed, thats the whole question, so i have no moon/earth/jupiter/pluto listing.

so 81.63 is right, but why is what i want to know now.

in other words

gravity on earth is approximately 9.8 newtons per kilogram. the weight is given in kilonewtons, so it should be weight*1000/9.8

sorry ignore the stuff i said before about kg, it was a brain fart
