# No slippage

Classical Mechanics Level pending

A spool of mass $$M$$ is resting on a horizontal surface. The spool has moment of inertia $$MG^{2}_{c}$$ about its axis of symmetry. Now, the spool is subjected to a rightward horizontal force of magnitude $$F,$$ applied at a distance of $$r$$ above the axis. Find the leftward frictional force $$f,$$ given that there is no slippage between the spool and the surface.
