A solid disk of mass m1 = 9.5 kg and radius R = 0.19 m is rotating with a constant angular velocity of ω = 30 rad/s. A thin rectangular rod with mass m2 = 3.3 kg and length L = 2R = 0.38 m begins at rest above the disk and is dropped on the disk where it begins to spin with the disk.

5) What is the final rotational energy of the rod and disk system?

A solid circular disk has a mass of 1.2 kg and a radius of 0.19 m. Each of three identical thin rods has a mass of 0.13 kg. The rods are attached perpendicularly to the plane of the disk at its outer edge to form a three-legged stool (see the drawing). Find the moment of inertia of the stool with respect to an axis that is perpendicular to the plane of the disk at its center. (Hint: When considering the...

A solid cylindrical disk has a radius of 0.19 m. It is mounted to an axle that is perpendicular to the circular end of the disk at its center. When a 40-N force is applied tangentially to the disk, perpendicular to the radius, the disk acquires an angular acceleration of 110 rad/s2. What is the mass of the disk? kg

A 3 kg disk of radius 0.25 m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center if mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft (the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia is of the shaft is negligible, a) what is the angular speed of the...
