A single conservative force acts on a 5.10-kg particle within a system due to its interaction with the rest of the system. The equation F, = 2x + 4 describes the force, where F, X X is in newtons and x is in meters. As the particle moves along the x axis from x = 0.94 m to x = 6.95 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 = 6.95 m if its speed is 3.00 m/s at x = 0.94 m J
