A puck of mass m = 71.0 g and radius r = 4.50 cm glides across an air table at a speed of = 1.50 m/s as shown in Figure a. It makes a glancing collision with a second puck of radius r = 6.00 cm and mass m = 115 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the pucks stick together and rotate after the collision (Figure b). m mo b (i) (a) What is the magnitude of the angular momentum of the system relative to the center of mass? Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation.
