Position vector of a spacecraft is given by point A (1200 km, 0.0059t rad), where t represents time variable. What is the tangential velocity of the spacecraft?

Two-Body Orbital Mechanics topics include: Two body problems, motion and conservation equations, celestial sphere concept, orbital elements, orbits, elliptical orbits, circular orbits, and hyperbolic orbits. Two-body orbital mechanics can be used to predict the motion and determine orbits of planets, moons, and satellites.  The two-body problem in classical mechanics is the prediction of the motion of two massive objects that are treated as point particles.

Two-body orbital mechanics can be used to predict the motion and determine orbits of planets, moons, and satellites. 

The two-body problem in classical mechanics is the prediction of the motion of two massive objects that are treated as point particles. In this problem, the two objects interact only with each other, and the only force affecting each object comes from the other. 

The two-body problem is interesting in astronomy because pairs of astronomical objects are often:
Moving rapidly in arbitrary directions
Widely separated from one another
Even more widely separated from other objects 

The two-body problem in general relativity is the determination of the motion and gravitational field of two bodies. The Kepler problem is a subset of the two-body problem. 

The two-body problem is an astrodynamics model that considers only two masses. One is usually a celestial body, and the other is usually a spacecraft.
