we have a shuttle in space taht is 518917 m above earth, if an astrinaut weight 900N, how much he will weight on the shuttle?(adsbygoogle = window.adsbygoogle || []).push({});

here is what i did so far,

the gravity on the shuttle = (6.67E-11* 6E24)/(518917+6.37E6)^2= 8.43m/ss

6.37E6 is the radius of earth in m

6.67E-11 is the universal gravitational system

6E24 is mass of earth in Kg

now his weight on earth is 900N --> 91.84 Kg

so in the shuttle he weights 91.84 / (9.8/8.43) = 79 Kg

i dont think that s right because if he weight 79Kg he is not gonna fly on the shuttle, and i think a gravity of 8.43 m/ss is too much for a shuttle that is 519 Km above earth ?!?!
