The force on the bicycle wheel can be resolved into two perpendicular componentsfriction parallel to the road (this must supply the centripetal force) and the vertical normal force (which must equal the systems weight). Because there is no friction over this portion of the track, the only energy conversion that takes place is between kinetic energy and gravitational potential energy. What is the maximum forceFthat can be applied for the two blocks to move together? M It takes 12 s to fall a distance of 0.60 m. Calculate the viscosity of the oil.
