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.

• Physics -

g(562km)= 9.8m/s^2 * (re/re+562km)^2

put re in km..

• Physics -

I know everything else but what is RE?

• Physics -

im guessing its the radius of earth?

• Physics -

so what would you do from there?

• Physics -

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.

• Physics -

yo fool cmon...

• Physics -

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