A puck of mass 80.0 g and radius 4.30 cm slides along an air table at a speed of 1.50 m/s as shown in the figure below. It makes a glancing collision with a second puck of radius 6.00 cm and mass 110.0 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the pucks stick together and spin after the collision. the angular momentum of the system relative to the position of the center of mass in the lab frame is = .0072 kg m^2 s^-1
What is the Angular Speed about the center of mass?
