Problem1. A 20-kg satellite is circling the Earth (RE = 6.37 x10° m, MẸ= 5.95x1024 kg) with a period of 5.0 hours. (a)What is the radius of its orbit? (b) What is the gravitational force on the satellite? (c) Find is the orbital speed of the satellite as it circles the Earth?

Geosynchronous satellite moves in a circular orbit around the Earth and completes one circle in the same time T during which the Earth completes one revolution around its own axis. The satellite has mass m and the Earth has mass M and radius R. In order to be geosynchronous, the satellite must be at a certain height h above the Earth’s surface.  a) Derive an expression for h in terms of m, M, R, T and constants.    b) Calculate the numerical value for h in meters.

A satellite is in a circular orbit around the earth. The period of the satellite is 20.3 hr. Calculate the radius of the orbit of the satellite. Data: Mass of the earth = 5.98.1024 kg. Submit Answer Tries 0/10 What is the speed of the satellite? Submit Answer Tries 0/10

A 200 kg satellite is placed into orbit around the Earth with a radius of 4.23 x 107 m. The mass of the Earth is about 6 x 1024 kg. (a) Find the gravitational force on the satellite.(b) Use the equation of centripetal force to find the speed of the satellite.
