Jessie is a 54 kg diver. she leaves the 10 meter platform with an angular momentum of 23 kgm^2/s. If she tucks and reduces her moment of inertia by 50% (she cuts it in half), what is her angular momentum (in kgm^2/s)? (Hint: What happens to angular velocity when no external force is applied and a person decreases moment of inertia, and does that change angular momentum?) Please round answer to 0 decimal places
