An inclined plane makes harmonic vibrations with high frequency along its
surface. What is the steady-state motion of a body on it? What is the average
velocity of this body over a large time if tanα≪ µ, where α is the angle of
inclination of the plane, µ is the coefficient of friction, v is the amplitude of
0
velocity of the inclined plane?
