1. A 10,000 kilograms satellite is launched from rest on the surface of the earth into a circular orbit 5000 kilometers above the Earth's surface. the radius is 6380 kilometres, and the mass is 5.9x10^24 kg.

1. find the potential energy of this satellite on the surface of the earth.
2. Find the orbit speed and kinetic energy of the satellite
3. find the total orbit energy of the satellite
4. find the work that must be done to put the satellite into orbit

1. Find the total orbit energy of the earth orbiting the sun

1. a rocket lifts off with no engine use from earth moving at 5.50 X 10 ^23 meters per second . the rocket has a mass 3.50 X 10 ^4 kg. find the maximum distance from the centre of the earth the rocket reaches before stopping. then find the distance the rocket traveled in kilometers

1. a 35,000 kilogram rocket lifts off with no engine use from the earth and travels to a maximum height of 36,000 kilometers above the earth surface. find the launch speed of the rocket

1. a 3.50x10^4 kg Rocket barely escapes from earth find its launch speed

1. a 15,200 kilograms space probe wishes to escape from the moon. find the required launch speed to barely escaped from the moon.

1. A 12,500 kilogram rocket orbits the earth at a distance of 4.20x10^3 km above the surface. what is the total orbit energy
