An unmanned multi-stage ARC rocket, carrying a weather satellite, is launched towards the planet Venus. At various altitudes above Earth, first the fuel tanks and then the booster rockets, fall back to Earth and the satellite continues to Venus. (i) Describe the changing acceleration of the rocket after launch. Venus is known as the 'Earth's sister' because of its similar size and gravity. It has a mass of 4.87 x 1024 kg and an average radius of 6060 km. As the 150 kg satellite slowly approaches the surface of Venus it is influenced by its gravitational field. (ii) Describe how the satellite gravitational potential energy changes as it is moving from an altitude of 5000 km to the surface of Venus. (iii) Calculate the gravitational field strength on the surface of Venus.
