Gravitational fields
Satellite A has twice the mass of satellite B, and rotates in the same orbit. Compare the two satellite's speeds.
Europa, a moon of Jupiter, has an orbital diameter of 1.34 x 109 m, and a period of 3.55 days. What is the mass of Jupiter?
At a distance of 14000 km from some planet's center, the acceleration of gravity is 32 m/s2. What is the acceleration of gravity at a point 28000 km from the planet's center?

It takes the planet Jupiter 12 years to orbit the Sun once. What is the average distance from Jupiter to the Sun? (The distance from the Earth to the Sun is 1.5 x 1011 m.)

An Earth satellite of mass m revolves at a height from the surface of the Earth. If R is the Earth's radius and g is the acceleration due to gravity at the surface of the Earth, then the velocity of the satellite is given by:
