A fire cracker is composed of a disk of mass m and radius R with 4 rockets, each of massm,, attached tangential to the edge of the disk. When it ignites,the rockets burn for a time At and each applies a constant thrust force F.What is the change in the fire cracker's angular momentum? What is its final angular velocity?

A uniform rod of mass 200 g and length 100 cm is free to rotate in a horizontal plane around a fixed vertical axis through its center, perpendicular to its length. Two small beads, each of mass 20 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod’s center, 10 cm from the axis of rotation. With the beads in this position, the rod is rotating with an angular velocity of 10.0 rad/s. When the catches are released, the beads slide outward along the rod.
