Unformatted text preview: described by a function y = h ( x ). If the spring is linear (with equilibrium position for the mass y eq ) and surface acts on the mass with an attractive force proportional to the inverse of the distance of the mass from the surface, derive the equation of motion for the mass (neglect gravity). a Draw the phase portrait. b How do the equations of motion change if the surface starts moving in the horizontal direction with small constant speed e ? c How would you use this system to measure the surface height h ( x )? 1...
