## Physics: Principles with Applications (7th Edition)

There is no net external torque on the diver, so her net angular momentum is conserved. $$L_{tuck}=L_{straight}$$ $$I_t \omega_t = I_s \omega_s$$ $$\omega_s=\frac{I_t }{I_s}\omega_t$$ $$\omega_s=\frac{1}{3.5}(\frac{2rev}{1.5s})=0.38\frac{rev}{s}$$
