The angular momentum of a freely rotating disk around its center is ldisk. you toss a heavy block horizontally onto the disk along the direction shown. friction acts between the disk and the block so that eventually the block is at rest on the disk and rotates with it. we will choose the initial angular momentum of the disk to be positive. 1) what is the total, the magnitude of the angular momentum of the disk-block system

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
