Problem
A particle moves along the x-axis while acted on by a single conservative force parallel to the x-axis. The force corresponds to the potential-energy function graphed in the figure 
. The particle is released from rest at point exttip{A}{A}.
What is the direction of the force on the particle when it is at point exttip{A}{A}?
At point exttip{B}{B}?
At what value of exttip{x}{x} is the kinetic energy of the particle a maximum?
What is the force on the particle when it is at point C?
What is the largest value of exttip{x}{x} reached by the particle during its motion?
What value or values of exttip{x}{x} correspond to points of stable equilibrium?
Of unstable equilibrium?
