A solid disk rotates in the horizontal plane at an angular velocityof 0.067 rad/s with respect to an axis perpendicular to the disk atits center. The moment of inertia of the disk is 0.10 kgImage for A solid disk rotates in the horizontal plane at an angular velocityof 0.067 rad/s with respect to an axis perp m2. From above,sand is dropped straight down onto the rotating disk, so that athin uniform ring of sand is formed at a distance of 0.40 m fromthe axis. The sand in the ring has a mass of 0.50 kg. After all the sand is in place, what is the angular velocity of thedisk?
