To determine the coefficient of friction between a block of mass 1.0 kg and a 100 cm long surface, an experimenter places the block on the surface and begins lifting one end. The block just begins to slip when the end of the surface has been lifted 60 cm above the horizontal. Find the static coefficient of friction.
