Chapter 6, Problem 6.27(choose chapter or problem)
The space probe Deep Space 1 was launched October 24, 1998, and it used a type of engine called an ion propulsion drive. An ion propulsion drive generates only a weak force (or thrust), but can do so for long periods of time using only small amounts of fuel. Suppose the probe, which has a mass of 474 kg, is traveling at an initial speed of 275 m/s. No forces act on it except the 5.60 102 -N thrust of its engine. This external force is directed parallel to the displacement , which has a magnitude of 2.42 109 m (see Figure 6.6). Determine the final speed of the probe, assuming that its mass remains nearly constant.
