A $$60\mathrm{kg}$$ diver in a full layout position with a total body radius of gyration with respect to her transverse principal axis equal to $$0.5\mathrm{m}$$, leaves the springboard with an angular velocity of $$5\mathrm{rad}/\mathrm{s}$$. What is the diver's angular velocity when she assumes a tuck position, reducing her radius of gyration to $$0.3\mathrm{m}$$ ? The problem is based on which principle? a. The conservation of energy b. The conservation of linear momentum c. The conservation of angular momentum d. The coefficient of angular velocity e. The coefficient of restitution What is/are constant in this problem? a. Mass b. Angular momentum c. Angular velocity d. Angular momentum and angular velocity What is the most appropriate formula? a. $$m_1{v}_1+m_2{v}_2=\left(m_1+m_2\right)v$$ b. $$\mathrm{M}=\mathrm{mv}$$ c. $$a=?/\mathrm{t}$$ d. $$\left(m^2?\right)1?{\left(m^2?\right)}_2$$ c. $${\mathrm{e}}^2=\mathrm{hb}/\mathrm{hd}$$ What is the numerical answer? a. $$13.9$$ b. 75 c. $$27.8$$ d. $$19.4$$ What are the connect units? a. deg b. rad c. $$\mathrm{rad}/\mathrm{s}$$ d. $$\mathrm{rad}/{\mathrm{s}}^2$$ e. $$\mathrm{m}$$ This is an example of the type of problem where radian-based units are required. a. True b. False
