A cylindrical disk has radius 0.5m, and mass 2kg.It is spinning counter clockwise at 300 rad/s. Asmaller concentric disk with radius 0.2m andmass 0.5kg is spinning clockwise at 400 rad/s.The smaller disk is then dropped onto the firstdisk, and sticks to it. What is the angularvelocity of the combined disk now?(A) 0(B) 273 rad/s,cw(C) 273 rad/s,ccw(D) 304 rad/s,cw(E) 304 rad/s,ccw
