A diver (such as the one shown in the figure(Figure 1) ) can reduce her moment of inertia by a factor of about 3.5 when changing from the straight position to the tuck position.
A) If she makes 2.0 rotations in 1.5
s when in the tuck position, what is her angular speed (rev/s) when in the straight position?

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....

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 1.0s . If she hadn't tucked at all, how many revolutions would she have made in the 1.8s from board to water?

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?

The moment of inertia of the human body about an axis through
its center of mass is important in the application of biomechanics
to sports such as diving and gymnastics. We can measure the body's
moment of inertia in a particular position while a person remains
in that position on a horizontal turntable, with the bodys center
of mass on the turntable's rotational axis. The turntable with the
person on it is then accelerated from rest by a torque that...

A trapeze artist performs an aerial maneuver. While in a tucked position, as shown in Figure A, she rotates about her center of mass at a rate of 6.15 rad/s. Her moment of inertia about this axis is 15.5 kg·m2. A short time later the aerialist is in the straight position, as shown in Figure B. If the moment of inertia about her center of mass in this position is now 34.9 kg·m2, what is her rotational speed?
