SUMMARY
The angular momentum of a rigid body system consisting of a 0.15 meter long, 0.15 kg thin rigid rod with a 0.22 kg mass on one end and a 0.080 kg mass on the other end, rotating at 1.7 rad/s, is calculated using the formula L = Iω. The moment of inertia (I) for point masses is determined by I = m1r1² + m2r2², where m1 and m2 are the masses and r1 and r2 are their respective distances from the center of rotation. The resulting angular momentum is 0.067 kg·m²/s.
