(a) A light, rigid rod of length { = 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 5.20 m/s. (Enter the magnitude to at least two decimal places in kg . m/s.) mg m Gi magnitude 18.2 V kg . m /s direction +Z (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 11.5 cm in diameter? (Round your answer to at least two decimal places.) 20.29 X kg . m2/s Need Help? Read It Master It
