During July 1994 the comet Shoemaker-Levy 9 smashed into Jupiter in a spectacular fashion. The comet really consisted of 21 distinct pieces, the largest of which had a mass of approximately 4.0 x 1012 kilogram and a speed of 6.0 x 104 m/s. Jupiter, the largest planet in the solar system, has a mass of 1.9 x 1027 kilogram and an orbital speed of 1.3 x 104m/s. If this piece of the comet had hit Jupiter head-on, determine what would have been the change (magnitude only) in Jupiter's orbital speed (not its final speed)?
Consider a plane that flies due east on a trip, and then returns due west following the same exact route. Imagine also that there are no winds in each trip. Flying due east, the plane flies with the rotation of the Earth, while flying due west..
