A wheel of radius

R

slides to the right across a horizontal surface while rotating more slowly than the rate required for rolling without slipping (so that

v>R\omega

for its center of mass speed

v

and angular speed

\omega

). Identify the type of friction acting on the wheel and state its direction.
