A single conservative force acts on a 5.00 kg particle. The equation Fx = (2x + 4) N describes this force, where x is in meters. As the particle moves along the x axis from x = 1.40 m to x = 7.00 m, calculate the following.

Your question is incomplete, but i assume they want you to calculate the work performed on the particle as it moves through that distance. That would be the integral of Fx dx from x=1.4 to 7.0
