Ann performs three different dives and rotates through the same number of revolutions in the same amount of time in all three dives. In all the dives, Ann’s positions at takeoff and just before water entry are identical layout positions. In dive 1 she is in a layout position in midflight. In dive 2 she is in a tuck position in midflight. In dive 3, she is in a pike position in midflight. Select which dive Ann has the smallest mass moment of inertia about the transverse axis (in/out of the page) of rotation.
