at what height above the earth's surface in a circular orbit have to travel in order to have an orbital period half that of a geosynchronous satellite's period? (a geosynchronous satellite orbits above the equator so that it is above the same location on the earth's surface at...

A satellite is placed between the Earth and the Moon, along a straight line that connects their centers of mass. The satellite has an orbital period around the Earth that is the same as that of the Moon, 27.3 days. How far away from the Earth should this satellite be placed?

**physics...**

A satellite moves in a circular orbit around the Earth at a speed of 5661 m/s. (a) Determine the satellite's altitude above the surface of the Earth. i'm using the equation Gm/(r+h)=9.8 where h=altitude and i keep coming up with the wrong answer.

An Earth satellite moves in a circular orbit 946 km above Earth's surface with a period of 103.8 min. What are (a) the speed and (b) the magnitude of the centripetal acceleration of the satellite? I got an answer of 7388.897 m/s for part a, but I'm stuck on part b

A satellite is orbiting the earth just above its surface. The centripetal force making the satellite follow a circular trajectory is just its weight, so its centripetal acceleration is about 9.81 m/s2 (the acceleration due to gravity near the earth's surface). If the earth's ...
