24 4 points Conservation of angular momentum: A disk with moment of inertia I1 = 3kgm rotates about a frictionless, vertical axle with angular speed wi = 8Rad/s. A second disk, this one having moment of inertia 12 = 1kgm and initially not rotating, drops onto the first disk. Because of friction between the surfaces, the two eventually reach the same angular speed W2 . What is w2? 13 Before After 24 Rad/s 12 Rad/s 6 Rad/s 16 Rad/s 4...

Disk A, with n mass of 2. 0 kg and a radius of 90 cm, rotates clockwise about a frictionless vertical axle at 20 rev/g. Disk B, also 2.0 kg but with a radius of 20 cm, rotates counterclockwise about that same axle, but at a greater height than disk A, at 20 rev/s. Disk B slides down the axle until it lands on top of disk A, after which they rotate together. After the collision what is magnitude of...

Adisk slides toward a motionless stick on a frictionless surface (figure below). The disk strikes and adheres to the stick and they rotate together pivoting around the rail. Angular momentum is conserved for this inelastic collision because the surface is frictionless and the unbalanced external force at the tail exerts no torque Before M Nal (plot 0.100 m from the il Consideratuation where the disk as a masof 515 (a) What is the angula velocity in rad/s) of the two...

A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...
