A thin meter stick of mass 150 g rotates around an axis perpendicular to the stick’s long axis at an angular velocity of 240 rev/min. What is the angular momentum of the stick if the rotation axis (a) passes through the center of the stick? (b) Passes through one end of the stick?

A sanding disk with rotational inertia 5.1 x 10³ kg-m² is attached to an electric drill whose motor delivers a torque of magnitude 38 N-m about the central axis of the disk. About that axis and with torque applied for 33 ms, what is the magnitude of the (a) angular momentum and (b) angular velocity of the disk? (a) Number i Units (b) Number i Units

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.)

A sanding disk with rotational inertia 3.5 x 103 kg-m? is attached to an electric drill whose motor delivers a torque of magnitude 40 N-m about the central axis of the disk. About that axis and with torque applied for 34 ms, what is the magnitude of the (a) angular momentum and (b) angular velocity of the disk? (a) Number Units (b) Number Units >
