A solid 11-kg cylinder rolls without slipping on a rough surface. At an instant when its center of gravity has a speed of 6.6 m/s. Determine:
a) the kinetic energy due to the motion of the center-of-mass. (ignoring rotation)
b) the kinetic energy due to rotation of the block about its center-or-mass.
c) the total kinetic energy.
