A bullet with mass of 25 grams traveling at speed of 185m/s hits the end of a rod as shown. The rod has a mass of 3 kg and a length of 80 cm, and it is free to spin about a perpendicular axis located at its center. If the bullet remains stuck in the end of the rod, what will be the angular speed of the rod after the bullet hits it? Let MM be the mass of the rod and mm be the mass of the bullet. The moment of inertia of a rod rotating about a perpendicular axis through its center is (1/12)ML2.(1/12)ML2. (Hint: After the bullet is embedded in the rod, it contributes m(L/2)2m(L/2)2to the moment of inertia of the rod.)

On average, both arms and hands together account for 13% of a person's mass, while the head is 7.0% and the trunk and legs account for 80%. We can model a spinning skater with her arms outstretched as a vertical cylinder (head, trunk, and legs) with two solid uniform rods (arms and hands) extended horizontally. Suppose a 75.0 kg skater is 1.80 m tall, has arms that are each 66.0 cm long (including the hands), and a trunk that can be modeled as being 33.0 cm in diameter. If the skater is initially spinning at 82.0 rpm with her arms outstretched, what will her angular velocity ?2 be (in rpm) after she pulls in her arms and they are at her sides parallel to her trunk? Assume that friction between the skater and the ice is negligble.
A uniform thin rod of length 0.78 m and mass 3.3 kg can rotate in a horizontal plane about a vertical axis through its center.
