A single conservative force acts on a 4.90-kg particle within a system due to its interaction with the rest of the system. The equation Fx = 2x + 4 describes the force, where Fx is in newtons and x is in meters. As the particle moves along the x axis from x = 0.96 m to x = 4.90 m, calculate the following (a) the work done by this force on the particle J (b) the change in the potential energy of the system J (c) the kinetic energy the particle has at x = 4.90 m if its speed is 3.00 m/s at x = 0.96 m J
