(a) 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 5.60 m/s. (Enter the magnitude to at least two decimal places in kg⋅m2/s. ) magnitude kg⋅m2/s direction (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 14.0 cm in diameter? (Round your answer to at least two decimal places. ) kg⋅m2/s
