A ball with radius 12cm rolls on a level surface, and the translational speed of the center of mass is 0.35 m/s.
What is the angular speed about the center of mass if the ball rolls without slipping?

in a .12*2*PI path, it has rolled once.
time= distance/speed= 12*2*PI/.35 s
angulur apeed= 2PI/time
time= distance/speed= 12*2*PI/.35 s
angulur apeed= 2PI/time
