Astronomers can detect extrasolar planets by observing the slightwobble of stars due to the gravitational forces between the starsand the planets. The Sun wobbles about the center of mass of the solar system.
Find the position of the center of mass by including the Sun,Jupiter, and Saturn, which make up most of the solar system's mass.Assume that the three are in line with each other, with bothplanets on one side of the center of mass.
An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. What is the velocity of the more massive fragment
