In Figure, three particles of mass m = 23 g are fastened to three rods of length d = 12 cm and negligible mass. The rigid assembly rotates around point O at the angular speed `omega=0.85rad//s`. About O, what are (a) the rotational inertia of the assembly, (b) the magnitude of the angular momentum of the middle particle, and ( c) the magnitude of the angular momentum of the assembly?

Explanation

(a) `4.6xx10^(-3)kg*m^(2)`, (b) `1.1xx10^(-3)kg*m^(2)//s`, ( c) `3.9xx10^(-3)kg*m^(2)//s`
