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 22 kg⋅m^2. She then tucks into a small ball, decreasing this moment of inertia to 4.2 kg⋅m^2. While tucked, she makes two complete revolutions in 2.1 s. If she did not tuck, how many revolutions would she have made in the same time?

A diver leaves the platform with her body straight. Her body is in a relatively slow rotation, with an angular speed of 4.0 rad/s. She then tucks into a pike position, with her body essentially folded in half. When straight her moment of inertia is 13.5 kg·m2, and when in the pike position it is 3.4 kg·m2. The next two questions have to do with this diver. Calculate her angular momentum when straight. a. 6 kg·m2/s b. 39 kg·m2/s c....
