A light rigid rod 1.00 m in length joins two particles, with masses 4.00 kg and 3.00 kg, at its ends. The combination rotates in the xy plane about a pivot through the center of the rod. Determine the angluar momentum of the system about the origin when the speed of each particle is 5.00 m/s.
never mind. i got this one.

A light, rigid rod 1.039m in length joins two particles with masses 3.65kg and 4.94kg at its ends. The combination rotates in the xy plane about a pivot through the centre of the rod. Determine the angular momentum of the system about the origin when the speed of each particle is 5.69m/s.
