How Long Does a Satellite Take to Orbit Earth at 325 km Altitude?

[Klee91]

Homework Statement

A satellite orbits Earth at an altitude of 325 km above the planet's surface. what is the oribital period? (radius of Earth =6.38 x 10 ^ 6 meters, mass of Earth = 5.98 x 10^24 kg)

Homework Equations

Net force = 4 pi^2r/T^2 Fg=Gm1m2/r^2

The Attempt at a Solution

4pi^2r/T^2 = gm1m2/r^2

Homework Equations

Net force = 4 pi^2r/T^2

This is not correct. Check the dimensions. This has the dimensions of distance/time^2.

Fix that and you will have the problem solved.
