We have a disk that is 1.49 kg and is traveling at 3.18 m/s to the right. It hits the end of a stick with a mass of 1.61 kg and an overall length of 3.2 m. The stick was originally oriented so that its long axis was perpendicular to the path of the disk, but it rotates after the collision. However, the disk continues moving along the same path after the collision. Assume that the collision is perfectly elastic, there is no friction, and the disk has an insignificant width. 1. Find the speed of the disk after collision. 2. Find the angular speed of the stick after collision.
