. A disk slides toward a motionless stick on a frictionless surface.
b. The disk hits the stick at one end and adheres to it, and they rotate together, pivoting around the nail.
Suppose the disk in the picture above has a mass of 50.0g and an initial velocity of 30.0ms when it strikes the stick that is 1.20m long and 2.00kg at a point 1.00m from the pivot. What is the angular velocity (in rads ) of the two after the collision?
