In 2006 NASA launched the New Horizons spacecraft with the mission to explore and photograph the mysterious dwarf planet Pluto. The New Horizons spacecraft spent almost a decade flying towards the edge of our solar system before reaching Pluto. Describe the forces acting on the New Horizons spacecraft during its launch in 2006 and during its trip through the solar system to reach Pluto. Be sure to discuss all the forces acting on the spacecraft during these two different times, including the net force.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

The answer should be a.
