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 disc angular momentum is
And the angular velocity is
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
