What is the force of gravity at 220 miles above Earth's surface? Calculate how much of a g force the astronauts are actually experiencing. The solution for this math problem is a percentage.
You can calculate it using the Algebraic equation: gr = R2/r2 x g
R = the radius of the planet
r = the distance from the center of mass of the planet to the center of mass of the object in orbit
g = the gravitational attraction of the planet on objects on its surface
gr = the gravitational attraction of the planet as felt on the less massive object

The gravitational attraction of the Earth on the surface is 1g.
the Equatorial radius of the Earth in kilometers is 6378.1

  1. you are given to use:

    gr= Re^2/(Re+ alt)^2 * g
    is there any reason you can't do that?

    of course, convert 220 miles to km
