Angular velocity of a satellite

Click For Summary

Homework Help Overview

The problem involves calculating the angular velocity of a satellite orbiting the Earth. The satellite's mass, height above the Earth, and relevant constants such as the mass of the Earth and gravitational constant are provided.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the gravitational force equation and its application to the problem. There are attempts to clarify the role of the satellite's mass and the correct interpretation of the given variables.

Discussion Status

Some participants have offered guidance on the equations to use and have prompted the original poster to share their calculations for further review. There is an ongoing exploration of the assumptions involved in the problem setup.

Contextual Notes

Participants note potential confusion regarding the inclusion of the satellite's mass in the calculations and the correct height measurement in meters. The original poster's multiple-choice options are also mentioned as a point of concern.

Homework Statement



A 5.00x10^3kg is orbiting the Earth in a circular path. The height of the satellite above the Earth is 8.00x10^2km what is the magnitude of the angular velociy?
Mass of earth: 5.98x10^24kg
radius of Earth plus satellite:6380800m
G:6.674x10^-11

Homework Equations



Gm1m2/r^2=v^2/r

The Attempt at a Solution


I know the satellite isn't involved I keep getting 1.23x10-3 but it's not any of the choices for multiple choice. Can anyone explain how to do this problem
 
Physics news on Phys.org
do u mean with g the gravitacional forces
 
G the gravitational constant
 
try it with this gm1m2/r2=v2/r then get into this gm1m2 x r = v2 x r2

Hi crazuiee! Welcome to PF! :smile:

(try using the X2 and X2 tags just above the Reply box :wink:)

Leave out m2, and that's correct :wink:

(But did you add just 800 metres? :redface:)

Show us your full calculations if you want us to check for the mistake. :smile:
 
oh right about m2 tim dident notice that
