Auniform flat disk of mass m and radius r rotates about a horizontal axis through its center with angular speed.
(a) what is its angular momentum?
(b) a chip of mass m breaks off the edge of the disk at an instant such that the chip rises vertically above the point at which it broke off (fig. 10-29). how high above the point does it rise before starting to fall?
(c) what is the final angular speed of the broken disk?
