Is this a Kepler law problem?

A satellite hovers over a certain spot on the equator of (rotating) Pluto. What is the altitude of its orbit (called a "synchronous orbit")?

You need to know:
1.Mass of Planet Pluto.

2.The 2-nd law of dynamics.

3.The law of gravitational attraction.

4.The period of rotation around its axis for the planet Pluto.

ok thx brb , sheesh this is killing me.

[CinderBlockFist]

Well i know

Mass of Pluto = 1.196 x 10 ^ 22 kg

Period of Rotation = 6.39 days

I don't know where i go from there?

[dextercioby]

U'll need the \omega=\frac{2\pi}{T}

So express the T (period in seconds).Then find the angular velocity and then appy the 2-nd law of dynamics...

[CinderBlockFist]

Is 2nd law of dynamics, you mean Newtons 2nd law? Because I haven't taken dynamics class yet.

[dextercioby]

Yes,of course.Report any bad results,if any.
