The only force acting on a 1.8-kg body as it moves along the x axis is given by F_x = -(3.0x)N,where x is in m.If the velocity of the body at x = 0 is v_x = +8.0 m/s,at what value of x will the body have a velocity of +4.0 m/s? A)5.7 m B)5.4 m C)4.8 m D)4.1 m E)6.6 m

The work-energy principle states that the work done by the force is equal to the change in kinetic energy. By integrating the force function and equating it to the change in kinetic energy, we find that the body will have a velocity of +4.0 m/s at x = 5.4 m.
