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?

A 500.0 g bird is flyinghorizontally at 2.25 m/s, notpaying much attention, when it suddenlyflies into a stationary verticalbar, hitting it 25.0 cm below the top(Fig. ). The bar is uniform,0.750 m long, has a mass of 1.50 kg,and is hinged at its base. The collisionstuns the bird so that it justdrops to the ground afterward (butsoon recovers to fly happily away).What is the angular velocity of the bar (a) just after it is hit by the birdand (b) just as it reaches the ground?
A 500.0 g bird is flying horizontally at 2.25 m/s, not paying much at- tention, when it suddenly flies into a stationary vertical bar, hitting it two-thirds of the way up from the bottom. The bar is uniform and very thin, is 0.750 m long, has a mass of 1.50 kg, and is hinged at its base. The collision stuns the bird so that it just drops to the ground afterwards (but soon recovers and flies away). a) Using conservation of total angular momentum, determine the angular velocity of the bar just after it is hit by the bird. b) What numerical fraction of the bird's initial kinetic energy is converted to other forms of energy during the collision?
A 15.0 kg bucket of water is suspended by a very lightrope wrapped around a solid uniform cylinder 0.300 m in diameter withmass 12.0 kg. The cylinder pivots on a frictionless axle through its center.The bucket is released from rest at the top of a well and falls 10.0 mto the water. With what speed does the bucket strike the water? What isthe time of fall?

The 0.61×1.00-m lid ABCD of a storage bin is hinged alongside AB and is held open by looping cord DEC over a frictionless hook at E. If the tension in the cord is 70 N, determine the moment about each of the coordinate axes of the force exerted by the cord at D.
. Johnny Manziel has decided that he’s a terrible quarterback (he’s pretty mad about it) andwants to become a kicker, but he’s concerned about the shoe he has chosen to kick withand how it will impact the inertia of his leg. The moment of inertia of the lower leg andfoot about an axis through the knee joint is 0.20 kg·m2. What is the moment of inertia ofthe leg and foot about the knee joint if a 0.50 kg shoe is worn on the foot? Assume thatthe shoe’s mass is all concentrated in one point 45 cm from the knee joint.0.30 kg·m2
