But one can take a swing about a celestial body. This maneuver in NASAese is called a slingshot encounter. Say we have a space probe on Jupiter’s orbital path opposite to Jupiter’s motion. The path can be regarded as straight line over the distance scale of our problem. The probe mass has m = 1000 kg and Jupiter has m Ju = 1 . 8988 × 10 27 kg ≈ 318 Earth masses. The probe velocity v probe i = − 10 km / s and Jupiter’s velocity v Ju i = 13 . 1 km / s: both velocities are relative to the Sun’s rest frame. The encounter is planned such that, if all goes well, the probe does 180 ◦ swing around Jupiter (i.e., a U-turn). Regarding the encounter as a 1-dimensional elastic collision what is the outgoing probe speed? Now why does NASA uses slingshot shot encounters? Give two reasons. 010 qfull 00400 2 5 0 moderate thinking: teenagers, symmetrical coll.
