C. A disk (mass M, radius R) is spinning clockwise at an angular speed wi = 10 rad/s when a second, smaller disk the same mass but half the radius is dropped on it. The M, R /2 smaller disk is initially not spinning. What is the final angular speed of the two disks? Hint: You will need information that is written at the top of the first page! M. R Initial Ang.

How fast and in what direction should the smaller disk be spinning in order for the two of them to stop spinning after the smaller disk is dropped on the larger disk? Counterclockwise
