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 18 kg . m2. She then tucks into a small ball, decreasing this moment of inertia to 3.6 kg . m2. While tucked, she makes two complete revolutions in 1.0 s. If she hadn’t tucked at all, how many revolutions would she have made in the 1.5 s from board to water?
