Problem
A rigid wheel rolls to the right on a horizontal surface without slipping, but air resistance is causing its speed to decrease. Which of the following identifies the frictional force exerted by the surface on the wheel?
(a) Static friction directed to the right
(b) No frictional force acts because the wheel does not slide
(c) Static friction directed to the left
(d) Kinetic friction directed to the left
