Asingle conservative force acts on a 5.00-kg particle within a system due to its interaction with the rest of the system. the equation fx 5 2x 1 4 describes the force, where fx is in newtons and x is in meters. as the particle moves along the x axis from x 5 1.00 m to x 5 5.00 m, 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 x 5 5.00 m if its speed is 3.00 m/s at x 5 1.00 m.
