A solid disk, spinning counter-clockwise, has a mass of #7 kg# and a radius of #3 m#. If a point on the edge of the disk is moving at #16 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
For a disc rotating with its axis through the centre and perpendicular to its plane, the moment of inertia ,
So, the Moment of Inertia for our case,
the angular velocity (
So, the Angular velocity (
Hence, the Angular Momentum =
