A solid disk, spinning counter-clockwise, has a mass of #3 kg# and a radius of #3 m#. If a point on the edge of the disk is moving at #8 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
The angular momentum is given by
The moment inertia of a disc is given by
Also we use the formula
And the angular momentum is
