A rotational inertia for a driver in a pike position is about 15.5 kg*m^2; it is only 8.0 kg*m^2 in a tuck position.
a) If the diver gives himself an initial angular momentum of 106 kg*m^2/s as he jumps off the board, how many turns can he make when jumping off a 10.0-m platform in a tuck position?
b) How many in a pike position? (Assume that the diver jumps horizontally off the platform - the diver falls from a height of 10.0 m.)
