The force on a particle, acting along the x axis, varies as shown in the figure.

A.) Determine the work done by this force to move the particle along the x axis: from x = 0.0 to x = 10.0m.

B.) Determine the work done by this force to move the particle along the x axis: from x = 0.0 to x = 15.0m.

The net force exerted on a particle acts in the positive x direction. Its magnitude increases linearly from zero at x=0, to 430 N at x = 3.4 m . It remains constant at 430 N from x = 3.4 m to x = 6.1 m , and then decreases linearly to zero at x = 13.3 m .

Determine the work done to move the particle from x=0 to x = 13.3 m graphically, by determining the area under the Fx versus x graph.
