FIGURE 8-11
-Fig. 8-11 shows the potential energy of an object as a function of position. Determine the force as a function of position.
A) F(x) = -2.0 N for -5.0 m < x < -2.0 m 0 for -2.0 m < x < 1.0 m
-1.0 N for 1.0 m < x < 5.0 m
B) F(x) = 2.0 N for -5.0 m < x < -2.0 m 0 for -2.0 m < x < 1.0 m
1.0 N for 1.0 m < x < 5.0 m
C) F(x) = (-2.0 N) x for -5.0 m < x < -2.0 m 0 for -2.0 m < x < 1.0 m
(-1.0 N) x for 1.0 m < x < 5.0 m
D) F(x) = (-1.0 N) x2 for -5.0 m < x < -2.0 m (-1.0 N) x for -2.0 m < x < 1.0 m
(-0.50 N) x2 for 1.0 m < x < 5.0 m
E) The force cannot be determined from the information presented in the graph.
