A cylinder of radius R = 6.0 cm is on a rough horizontal surface with Friction coefficient .30 and the rotational inertia for rotation about the axis is given by MR^2/2, where M is its mass. Initially it is not rotating but its center of mass has a speed of 7.0 m/s. After 2.0s the speed of its center of mass and its angular velocity about its center of mass, respectively, are:
a. 1.1m/s, 0
B. 1.1m/s, 19rad/s
C. 1.1m/s, 98rad/s
D. 1.1m/s, 200rad/s
E. 5.9m/s, 98rad/s
