You are explaining why astronauts feel weightless while orbiting in the space shuttle. Your friends respond that they thought gravity was just a lot weaker up there. Convince them and yourself that it isn't so by calculating the acceleration of gravity 562 km above the Earth's surface in terms of g.

g(562km)= 9.8m/s^2 * (re/re+562km)^2
put re in km.. 
I know everything else but what is RE?

im guessing its the radius of earth?

so what would you do from there?

Plug in the radius of the earth which is 6.38*10^6 meters. you can convert the 562 km to 562000meters. plug in and solve.

yo fool cmon...

how do you solve without the mass of the space shuttle?
