Calculate the magnitude of the total angular momentum of the woman–disk system. (assume that you can treat the woman as a point. express your answer to two significant figures and include the appropriate units.
I of disk = 1/2MR² = (0.5)(230)(4.0)² = 1840 kgm² I of disk-woman system = I = 1/2MR² + md² = (50)(4.0)² = 1840 + 800 = 2640 kgm² L = Iw = (2640)(0.80)(2π) = 13,270 ≈ = 13,000 kgm²/s ANS
