A puck of mass 80.0 g and radius 4.50 cmslides along an air table at a speed of 1.50 m/s as shown in FigureP11.34a. It makes a glancing collision with a second puck of radius6.00 cm and mass 105.0 g (initially atrest) such that their rims just touch. Because their rims arecoated with instant-acting glue, the pucks stick together and spinafter the collision
