After this dunking, the dragonflies gain altitude, and then spin rapidly at about 1100 rpm to spray the water off their bodies. When the dragonflies do this "spin-dry," they tuck themselves into a "ball" with a moment of inertia of 1.7 x 107 kg-m² Part A How much energy must the dragonfly generate to spin itself at this rate?
