How Does Body Position Affect a Diver's Ability to Perform Somersaults?

[louie3006]

I need help seriously anyone can help, because i honestly have no clue.

Q # 1. why is it possible for a high diver to execute more front somersaults in the tuck position than in the layout position?

Q # 2. An air hockey puck is whirling on the end of a string that passes through a small hole in the center of the table. what happens to the speed of the puck as the string is slowly pulled down through the hole?

Q # 3 as you walk from the center of a merry go round toward the outer edge, the merry go round slows. IS angular momentum conserved?

What happens to the diver's moment of inertia when they tuck themselves in? How does the diver's moment of inertia relate to his/her angular momentum?Same basic concept for Q3
