A 100 g particle experiences the one-dimensional, conservative force Fx shown in the figure.

Let the zero of the potential energy be at x = 0 m.What is the potential energy at x = 1.0, 2.0, 3.0, and 4.0 m? Hint: Think about the definition of potential energy and the geometric interpretation of the work done by a varying force.

Suppose the particle is shot toward the right from x = 1.0 m with a speed of 24 m/s. Where is the particles turning point?
