Angular Momentum: Three solid, uniform, cylindrical flywheels, each of mass 65.0 kg and radius 1.47 m, rotate independently around a common axis through their centers. Two of the flywheels rotate in one direction at 8.94 rad/s, but the other one rotates in the opposite direction at 3.42 rad/s. Calculate the magnitude of the net angular momentum of the system.
A. 1020 kg ? m2/s
B. 1500 kg ? m2/s
C. 975 kg ? m2/s
D. 940 kg ? m2/s
