This time we have a non-rotating space station in the shape of a long thin uniform rod of mass 4.23 x 10^6 kg and length 660 meters. Small probes of mass 9078 kg are periodically launched in pairs from two points on the rod-shaped part of the station as shown, launching at a speed of 3658 m/s with respect to the launch points, which are each located 235 m from the center of the rod. After 12 pairs of probes have launched, how fast will the station be spinning?

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.
