A solid disk, spinning counter-clockwise, has a mass of #4 kg# and a radius of #3/7 m#. If a point on the edge of the disk is moving at #5/9 m/s# in the direction perpendicular to the disk's radius, what is the disk's angular momentum and velocity?
Like linear momentum;
p = mv.
Angular momentum equals the angular component of mass multiplied by the angular velocity,
L (angular momentum) = I (inertia) x w (angular velocity).
Inertia of a solid disk =
Angular velocity equals tangential velocity divided by radius.
