SUMMARY
The angular momentum of a rotating disk can be calculated using the formula L = Iω, where I is the rotational inertia and ω is the angular velocity. For a disk with a mass of 1.8 kg and a radius of 0.026 m rotating at 600 RPM, the calculated angular velocity is 62.83 rad/sec. The user initially calculated the angular momentum as 0.076 kg*m²/s, but the correct answer is 0.038 kg*m²/s, indicating a potential error in the calculation of the rotational inertia or the conversion of units.
