moment of inertia
A puck of mass 79.1 g and radius 4.45 cm slides along an air table at a speed of v = 1.47 m/s,as shown in the figure below.It makes a glancing collision with a second puck of radius 6.92 cm and mass 140 g (initially at rest) such that their rims just touch.The pucks stick together and spin after the collision (b).What is the angular momentum of the system relative to the center of mass?What is the angular velocity about the center of mass?
