The potential energy function for a system is given by

U(x) = 3x^3 - 2x^2 - 6x
where x is in meters and U is in Joules.
a) Determine the force Fx as a function of x
b). For what values of x is the force equal to zero
c). Plot U(x) versus x and Fx versus x, and indicate thepointsof stable and unstable equilibrium.
d). If a particle moves from x= 2m to x = 4m, find thechangein its kinetic energy. Assume that the only force acting ontheparticles is the force found in part (a).

Please be sure .

A single conservative force acts on a particle within a system due to its interaction with the rest of the system. The equation describes the force, where is in newtons and is in meters. As the particle moves along the axis from to , calculate (a) the work done by this force on the particle, (b) the change in the potential energy of the system, and (c) the kinetic energy the particle has at if its speed is at .

Particle a has mass m, is initially located on the positive x axis at x =x0 and is subject to a repulsive force Fx from particle b. The location of particle b is fixed at the origin. The force Fx is inversely proportional to the square of the distance x between the particles. That is, Fx = A/x^2, where A is a positive constant. Particle a is released from rest and allowed to move under the influence of the force. Find an expresson for the work donw by the force on a as a function of x. Find both the kinetic energy and speed of a as x approaches infinity.
