Question:
Divers increase their spin by tucking in their arms and legs (Figure 11.32). Suppose the outstretched body of a diver rotates at 1.2 revolutions per second before he pulls his arms and knees into his chest, reducing his rotational inertia from \(9.4 \mathrm{~kg} \cdot \mathrm{m}^{2}\) to \(3.1 \mathrm{~kg} \cdot \mathrm{m}^{2}\). What is his rotational velocity after he tucks in his arms and legs?
Data from Figure 11.32
