A disk (Idisk = 12MR2) of mass 200kg and radius 2m is rotating at rad/s. A small object of mass 40 kg then collides with and sticks to the disk at a location halfway between the center and the edge.

(a) What is the new angular speed? (b) Was the collision elastic or inelastic?

A 2 kg mass attached to a 40 cm long string is hit so hard that it ends up moving in a (vertical) circle. If the tension in the string is 40 N when the mass is at its highest point, what is the speed of the mass at the lowest point?c
