A space probe is fired as a projectile from the Earths surface with an initial speed of 2.00 ? 10 4 m/s. What will its speed be when it is very far from the Earth? Ignore friction and the rotation of the Earth. A 1 000-kg satellite orbits the Earth at a constant altitude of 100 km. How much energy must be added to the system to move the satellite into a circular orbit with altitude 200 km? Discuss the changes in kinetic energy, potential energy, and total energy.
