A solid disk, spinning counter-clockwise, has a mass of #6 kg# and a radius of #2 m#. If a point on the edge of the disk is moving at #5/2 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
The relationship between instantaneous velocity, v and angular velocity,
Angular momentum is
So, the angular momentum,
I hope this helps,
