(a) A light, rigid rod of length 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 4.40 m/s. (Enter the magnitude to at least two decimal places in kg·m2/s.
(b) What I? What would be the new angular momentum of the system (in kg m2/s) if each of the masses were instead a solid sphere 11.5 cm in diameter?
