9) Consider two thin rods each of
length (L = 1.5 m) and mass 30 g, arranged on a frictionless
table as shown in the figure. The system rotates about a vertical
axis through point O with constant angular speed of 4.0 rad/s. What is
the angular momentum of the system about O?
A1 0.18 kg*m**2/s
A2 0.54 kg*m**2/s
A3 1.5
kg*m**2/s
A4 0.27 kg*m**2/s
A5 0.0
