A diver off the high board imparts an initial rotation with his body fully extended before going into a tuck and executing three back somersaults before hitting the water. If his moment of inertia before the tuck is 16.9kgm2 and after the tuck during the somersaults is 4.2kgm2 , what rotation rate must he impart to his body directly off the board and before the tuck if he takes 1.4 s to execute the somersaults before hitting the water?
Three children are riding on the edge of a merry-go-round that is 100 kg, has a 1.60-m radius, and is spinning at 20.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the child who has a mass of 28.0 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm?

Some dragonflies splash down ontothe surface of a lake to clean themselves. After this dunking, thedragonflies gain altitude, and then spin rapidly at about 1000 rpmto spray the water off their bodies. When the dragonflies do this“spin-dry,” they tuck themselves into a “ball” with a moment ofinertia of 2.6 * 10-7kg·m2. How much energy must the dragonflygenerate to spin itself at this rate?
