A very thin 2.0-kg disk with a diameter of 80 cm is mounted horizontally to rotate freely about a central vertical axis. On the edge of the disk, sticking out a little, is a small, essentially massless, tab or "catcher." A 2.0-g wad of clay is fired at a speed of 14.0 m/s directly at the tab perpendicular to it and tangent to the disk. The clay sticks to the tab, which is initially at rest, at a distance of...

A horizontal turntable is made from a uniform solid disk and is initially rotating with angular velocity of 7.1 rad/s about a fixed vertical axis through its center. The turntable has a radius of 0.23 m and a moment of inertia of 0.04761 kg m2 about the rotation axis. A piece of clay, initially at rest, is dropped onto the turntable and sticks to it at a distance d= 0.16 m from its center as shown in the figure. The...

Rigid rods of negligible mass lying along the y axis connect three particles. The system rotates about the x axis with an angular speed of 3.20 rad/s. An x y plane is shown. Three particles are all connected to each other by two rigid rods that are along the y-axis. The 4.00 kg particle is located at y = 3.00 m. The 2.00 kg particle is located at y = −2.00 m. The 3.00 kg mass is located at y...
