Assignment:
A puck of mass 80.0 g and radius 3.60 cm slides along an air table at a speed of 1.50 m/s as shown in Figure P11.34a. It makes a glancing collision with a second puck of radius 6.00 cm and mass 125.0 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.
(a) What is the angular momentum of the system relative to the center of mass?
________kg m2/s
(b) What is the angular speed about the center of mass after collision?
________rad/s
(c) What is the velocity of the center of mass?
________ m/s
(d) What is the final kinetic energy?
________ J
(e) How much energy is lost in the collision?
________J
