During July 1995 the comet Shemaker-Levy 9 smashed into Jupiter in a spectacular fashion. The comet actually consisted of 21 distinct pieces, the largest of which had a mass of about 4x1012 kg and a speed of 6x104 m/s. Jupiter, the largest planet in the solar system , has a mass of 1.9x1027 kg and an orbital speed of 1.3x104 m/s. If this piece of the comet had hit Jupiter head on , what would have been the change (magnitude only) in Jupiter's orbital speed(not its final speed)?
