Problem 1 (10 points) 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 ry plane about a pivot through the center of the rod (Fig. 1). Determine the angular momentum of the system about the origin when the speed of each particle is 5.00 m/s. Solution: A mg my Figure 1
