Homework Help: Physics

Posted by John on Saturday, January 22, 2011 at 10:44am.

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
