If she hadn’t tucked at all, how many revolutions would she have made in the 1.6s from board to water?
Problem 10.31 - Enhanced - with Solution
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 · m². She then
tucks into a small ball, decreasing this moment of
inertia to 3.6kg m2. While tucked, she makes two
complete revolutions in 1.0 s.
