A conservative force F(x) acts on a 2.0 kg particle that moves along an x axis. The potential energy U(x) associated with F(x) is graphed in Figure. When the particle is at x = 2.0m, its velocity is ?? 1.5 m/s. What are the(a) Magnitude and(b) Direction of F(x) at this on the(c) Left and(d) Right is the particle's speed at x =7.0m?
