A ball rolls without friction along a track of changing elevation (vertical coordinate). The total energy (red line) and potential energy U (blue curve) versus horizontal distance x is shown in the figure below. The unit of energy is J (1) per grid line) and the unit of distance is m (0.5 m per grid line). U 5 4 3 2 1 0 X 2 3 At x = 1 m, what is the force on the ball? +0.5 N 0 -1.0 N 0 +1.0 N -0.5 N 0 +2.0 N
