Homework Help: physics

Posted by Anonymous on Thursday, October 17, 2013 at 1:25pm.

A satellite with a mass of ms = 7.00 103 kg is in a planet's equatorial plane in a circular "synchronous" orbit. This means that an observer at the equator will see the satellite being stationary overhead (see figure below). The planet has mass mp = 8.59 1025 kg and a day of length T = 1.1 earth days (1 earth day = 24 hours).


(a) How far from the center (in m) of the planet is the satellite?

(b) What is the escape velocity (in km/sec) from this orbit?
