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 18kgm^2. She then tucks into a small ball, decreasing this moment of inertia to 3.6kgm^2. While tucked, she makes two complete revolutions in 1.1 s.

a-) If she hadn't tucked at all, how many revolutions would she have made in the 1.5 s

from board to water? Express your answer using two significant figures.
