A cylindrical disk of mass M = 4.60 kg and radius R = 0.250 m is sitting motionless on a fixed axis. A piece of putty of mass m = 1.25 kg moving with horizontal velo1city 2vo = 3.44 m/s strikes the edge of the disk and sticks to it as shown. After this, the cylinder and putty rotate together

clockwise as show

(a) What is the angular momentum of the disk/putty system just before the collision? (b) What is the angular momentum of the disk/putty system just after the collision? (c) What is the angular velocity (') of the disk/putty system just after the collision?

(d) For the angular velocity found in part (c) for the disk/putty system, how long will it take to make one complete revolution, i.e., what is the period T of rotation? Assume ' to be constant for the complete revolution.
