3 4 points Angular momenturn: A light, rigid rod of length 2 = 1m joins two particles, with masses mi = 3.00kg and my = 4.00kg, at its ends. The combination rotates in the x-y plane about a pivot through the center of the rod. What is the angular momentum of the system about the origin when the angular speed of each particle is w = 5.00 Rad/. Assume m and m2 are point masses and ignore the mass of...

Problem 1 Two identical pucks, each of inertia m, are connected to a rod of length 2r and negligible inertia that is pivoted about its center (that is, there is some sort of pin though its center, around which it can rotate without friction). A third puck of inertia m/2 strikes one of the connected pucks perpendicular to the rod with a speed vi. Assume the collision is elastic. (a) Draw a diagram of the situation, clearly labeling the direction...

1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the...

A long, uniform rod of mass 20.00 kg is pivoted at its top end. It is lifted a small angle and let go. When it reaches the very bottom of its swing, it is moving with angular speed ?o , and it has collision with a block of mass 3.000 kg that was originally at rest on a frictionless surface. After the collision the rod is seen to continue spinning in the same direction at 17.66 rad/s. As a result...
