A satellite of 400 Kg was originally placed into an orbit of radius 30,000 km and a period of 31 hours around planet Barigou. a) Deduce the expression of the mass of this planet in terms of the Universal constant G, the radius R and the period T. b) Calculate the value of new time period if the satellite was then put into its final orbit of radius 10,000 km. c) Estimate the change in the kinetic energy of the satellite from the first to the second orbits? d) Calculate the change in kinetic energy if it goes from the initial orbit to infinity.
