    Centripetal Acceleration of a satellite above a planet of the Earth's radius.

    Thanks for help. It has come to me now. 9.81 = v^2/6400000 So v = 7.9e3 ms-1 and so time for 1 orbit is (2pi)r/v

    Centripetal Acceleration of a satellite above a planet of the Earth's radius.

    The question has no mention of mass so this should not be used. All the information I have is in the original question. It is A satellite in low orbit around a planet with same radius as the Earth.

    Centripetal Acceleration of a satellite above a planet of the Earth's radius.

    Homework Statement A satellite is in orbit just above the surface of a spherical planet which has the same radius as Earth and the same acceleration of free fall at it's surface. Calculate: i) Speed ii) Time for 1 complete orbit. Radius of Earth = 6400km or 6400000m and accel. of free...
