The potential energy of a object constrained to the x axis is given by U(x)=3x2 - 2x3 , where U is in joules and x is in meters.
A) Compute the force associated with this potential energy function.
B) Assuming no other forces act of the object, at what positions is this object in equilibrium?
C) Which of these equilibrium positions are stable and which are unstable?
