A solid disk, spinning counter-clockwise, has a mass of #12 kg# and a radius of #6 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?
Angular velocity is given by the equation
It is in the units radians per second, or
Angular momentum is the product of angular velocity and mass, much like linear momentum is the product of linear velocity and mass, so
