Angular velocity when he left the diving board

Reference no: EM13657213

A diver can change his rotational inertia by drawing his arms and legs close to his body in the tuck position. After he leaves the diving board (with some unidentified angular velocity), he pulls him self into a ball as closely as possible and makes 2.21 complete rotations in 1.24 s. If his rotational inertia decreases by a factor of 2.99 when he goes from the straight to the tuck position, what was his angular velocity when he left the diving board?
