(30 points] A 0.5 kg ball experiences the one-dimensional, conservative force Fx as shown in Figure 1. The corresponding potential energy versus x is is shown in Figure 2. No friction involves throughout the path. The ball has a total energy of 60.0 J and the zero potential reference is at x = 0 m. [Answer in 3 significant figures] F. versus x. 30 25 15 10 10 F.
