How do you find the escape velocity for objects on the planet Venus?

When large communications satellites are positioned in geosynchronous orbit (GEO), they are first launched into low-Earth orbit (LEO) while mated to a transfer stage. A transfer stage is a rocket specifically designed to move (or transfer) satellites from LEO  to GEO. Compare the amount of energy it requires to transfer a 8,000 kg satellite from a 750 km altitude orbit to GEO with the amount of energy required to send a 8,000 kg spacecraft from the same LEO orbit to the Moon so that it can land on the surface of the Moon. Note that the Lunar spacecraft will need the same orbital speed as that of the Moon around the Earth so that the Moon doesn’t move away from the spacecraft before it has a chance to land.

For the gravitational field of a large massive object, such as the sun, what is the gravitational potential energy of a smaller mass very, very far away? O mgh O 42

Question: Three identical 5.6 kg spheres are located at 3 of the 4 corners (top left, top right, and bottom right) of a square whose sides are 2.8 m in length. How much work must be done on the gravitational field produced by the spheres in order to remove the top right sphere (place it at infinity)? Assume that the 2 spheres that are left behind (top left, bottom right) remain located on opposite corners of the square. A) 1.50 x 10-9 J B) 5.34 x 10-10 J C) 1.89 x 10-10 J D) 2.67 x 10-10 J E) 5.29 x 10-10 J OA E B. C.

Show that the gravitational potential energy of an object of mass at height on Earth is given by PEg = mgh.
