=
A single conservative force acts on a 10-kg
particle within a system due to its interaction with
the rest of the system. The equation F = (6x4 + -4x2
+ 2) describes the force, where F is in newtons and
x is in meters. As the particle moves along the x-
axis from x=3.14 m to x=7.95 m, calculate the
work done by this force on the particle.
Round your answer to 2 decimal places.
