A puck of mass m1 = 63.0 g and radius r1 = 4.10 cm glides across anair table at a speed of = 1.50 m/s as shown in Figure a. It makes aglancing collision with a second puck of radius r2 = 6.00 cm andmass m2 = 115 g (initially at rest) such that their rims justtouch. Because their rims are coated with instant-acting glue, thepucks stick together and rotate after the collision.
(a) What is the magnitude of the angular momentum of the systemrelative to the center of mass?
(b) What is the angular speed about the center of mass?
