The relative angle of the knee changes from 180 degrees (full extension) to 80 degrees during the knee flexion (down) phase of a squat exercise. If 10 complete squats are performed during a 30 second time period, what is the total angular speed?
(II) A diver (such as the one shown in Fig. 8–28) can reduceher moment of inertia by a factor of about 3.5 when changingfrom the straight position to the tuck position. If she makes2.0 rotations in 1.5 s when in the tuck position, what is herangular speed (rev /s) when in the straight position?

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?
