Problem
An object on a frictionless horizontal surface experiences a net horizontal force that depends on its displacement x (in meters) from point O:
F(x)={−30x30(x−0.04)(x≤0)(0<x≤0.08)
(a) Determine all values of x at which the object can be in equilibrium.
(b) For each equilibrium point, state whether it is stable or unstable, and justify your answer by referring to the direction of the force for small displacements.
