question 45

Multiple Choice

The first skater carries a 2-m pole that may be considered massless. As he passes the pole, the second skater catches hold of the end. The two skaters then go around in a circle about the center of the pole.
-What is their combined angular momentum about the center of the pole?

• A)2 kg . m²/s
• B)40 kg . m²/s
• C)80 kg . m²/s
• D)400 kg . m²/s
• E)800 kg . m²/s
