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 Figure (see attachment). It makes a glancing collision with a second puck of radius 6.00 cm and mass 140.0 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 (Fig. b).

kg Â· m2/s

(b) What is the angular speed about the center of mass?
