- What is the radius of geosynchronous orbit around the earth? (where the period of orbit is the same as the earths rotational period) Using the mass of the earth as me = 5.98 x 1024 kg and the sidereal day as 23 hours 56 minutes and 4.0905 s. Number UnitsA planet of mass 6 x 1024 kg is in orbit around a star of mass 2 x 1030 kg. If the distance between the planet and the star is 5 x 1011 m, what is the force exerted on this planet by the star?the mass of planet is 2.00 x 10 22 kg and the radius of the planet is 5.0 x 10 5 m what is the force of gravity on a 1.00 kg mass at the planets surface? What is the force of gravity on a 1.00 kg mass if it were 5.00 x 10 5 m above the planets surface?
- Taking the age of Earth to be about 4 ✕ 109 years and assuming its orbital radius of 1.5 ✕ 1011 m has not changed and is circular, calculate the approximate total distance Earth has traveled since its birth (in a frame of reference stationary with respect to the Sun).Taking the age of Earth to be about 4 ✕ 109 years and assuming its orbital radius of 1.5 ✕ 1011 m has not changed and is circular, calculate the approximate total distance Earth has traveled since its birth (in a frame of reference stationary with respect to the Sun).The moon Phobos orbits around Mars with a semi-major axis of 9376 km, and an orbital period of 7.65 hours. If NASA wanted to put a satellite in a circular orbit around Mars with an orbital period of 50.0 hours, what should the radius of the orbit be, in km?
- The radius of the Earth is about 6,000 km. My weight on the surface of the Earth is 1250 N. What would be my weight (how much force would the Earth exert on me) at a distances of 72,000 km measured from the center of the Earth?Calculate the period of a satellite orbiting a planet with the mass 8.7 x 1022 kg given the height of the satellite's orbit is 300 km and the radius of the planet is 2000 km. Provide your answer in Sl units.A satellite is in circular polar orbit around Earth at an altitude of 450 km – meaning it passes directly overhead of the North and South Poles. What is the magnitude and direction of the displacement vector when it is directly over the North Pole to when it is at 40° latitude? Earth’s radius is 6,370 km.

What is the orbital time of the satellite (expressed in hours)?The position of a planet that a closest to and farthest from the sun are called its perihelion and aphelion respectively. We know that the Earth orbits around the Sun (as one focus) in an elliptical orbit with the perihelion distance of 1.47 x 10^8 km and the aphelion distance of 1.52 x 10^8 km. Find the Cartesian equation of the elliptical orbit.A centripetal force of 175 N acts on a 1,450-kg satellite moving with a speed of 5,100 m/s in a circular orbit around a planet.
