The figure gives the acceleration of a 2.00kg particle as an applied force Fa moves it from rest along an x axis from x=0 to x=9.0m. The scale of the figure’s vertical axis is set by as=6.0m/s2. How much work has the force done on the particle when the particle reaches (a) x=4.0m, (b) x=7.0m, and (c) x=9.0m? What is the particle’s speed and direction of travel when it reaches (d) x=4.0m, (e) x=7.0m, and (f) x=9.0m?
