$10\mathrm{.}44$cdots A diver comes off a board with arms straight up and legs straight down, giving her a moment of inertia about her rotation axis of $18kg*m^2.$ She then tucks into a small ball, decreasing this moment of inertia to $3\mathrm{.}6kg*m^2.$ While tucked, she makes two complete revolutions in $1\mathrm{.}0$ s $.$ If she hadn't tucked at all, how many revolutions would she have made in the $1\mathrm{.}5$ s from board to water?
