Question

(a) A light, rigid rod of length ℓ = 1.00 m joins two particles, with masses m = 4.00 kg and m, = 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 7.60 m/s. (Enter the magnitude to at least two decimal places in kg. m²/s.) 

(b) What If? What would be the new angular momentum of the system (in kg. m²/s) if each of the masses were instead a solid sphere 13.0 cm in diameter? (Round your answer to at least two decimal places.)
