Question

A light, rigid rod of length l = 1.00 m joins two particles, with masses m1 = 4.00 kg and m2 = 3.00 kg, at its ends. The combination rotates in the xy plane about a pivot through the center of the rod (see figure below). Determine the angular momentum of the system about the origin when the speed of each particle is 8.00 m/s.

a) what is the magnitude in kg m^2/s

b) what is the direction
