A uniform disk of radius and mass rests on a horizontal, frictionless surface. A bullet of mass travels with speed 0in the horizontal plane when it strikes the outside edge of the disk and becomes embedded in the disk. After the collision, the disk-bullet system move with translational speed comand angular speed about the center of mass . All answers should be expressed in terms of any or all ,,and 0. Assume that ≫.(a) What is the final translational speed com?(b) What is the final angular speed ?(c) What is the ratio com/?

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
