A rod of length 10 m rotates about an axis perpendicular to its length and through its center. Two particles of masses m1 = 4.0 kg and m2 = 3.0 kg are connected to the ends of the rod. What is the angular momentum of the system if the speed of each particle is 2.5 m/s?

(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 4.80 m/s. (Enter the magnitude to at least two decimal places in kg · m2/s.) Two masses...

A rigid rod of mass 5.30 kg and length of 1.50 m rotates in a vertical (x,y) plane about a frictionless pivot through its center. Particles m_1 (mass=6.30 kg) and m_2 (mass=2.20 kg) are attached at the ends of the rod. Determine the size of the angular acceleration of the system when the rod makes an angle of 42.1° with the horizontal.

A uniform wire of mass M and length d rotates in a horizontal plane about an axis passing through its center. Two small beads, each of mass m, are placed on the wire; friction between the beads and the wire is negligible. The beads are initially held on the wire by catches at a distance d/4 on either side of the center, and the system rotates with angular speed ω0. The catches are then released, and the beads slide outward...
