A Cylinder of Radius R = 6

Multiple Choice

A cylinder of radius R = 6.0 cm is on a rough horizontal surface.The coefficient of kinetic friction between the cylinder and the surface is 0.30 and the rotational inertia for rotation about the axis is given by MR²/2, where M is its mass.Initially it is not rotating but its center of mass has a speed of 7.0 m/s.After 2.0 s the speed of its center of mass and its angular velocity about its center of mass, respectively, are:

A) 1.1 m/s, 0
B) 1.1 m/s, 19 rad/s
C) 1.1 m/s, 98 rad/s
D) 4.7 m/s, 78 rad/s
E) 5.9 m/s, 98 rad/s
