A student performed an experiment to prove the angular momentum conservation experiment using a rotating disk experiment. In this experiment a disk of mass =1kg and radius 1m was rotated initially at a speed of 40rot/s. While it was rotating, an identical disk was dropped on the top. By using conservation of angular momentum find the rotation speed of the combined system. Hint: Rotational Inertia of the disk of mass m and radius r is I=(1/2)mr2. Conservation of angular momentum,I1w1=I2w2 where I1 is the initial inertia of the disk and w1=40rot/s,I2=2I1.Solve for w2

The figure shows a device that can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.872 m, and rotating with an angular speed of 101 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is = 0.268 rad. From these data, determine the speed of the bullet. Number IN Bullet Units Motor
