## Homework Statement

A 135 kg satellite experiences a gravitational force by the Earth of 960 N. What is the radius of the satellite's orbit. And altitude? I already found the radius and I came up with 7489.99 km. I just need help finding the altitude.

## Homework Equations

Equation for period: T= 2∏ times the square root of (r^3) / (GMe)

Period= how long it takes to go around once.

From this step what do I do next?

## The Attempt at a Solution

For T I did 2∏ times the square root of (4.2E11) / (3.99E14)

I got 4.2E11 but taking the radius I got up above (7489.99) and then curbing it. I got 3.99E14 by taking G (6.67E-11) times Me (5.98E24).
