An object slides along a curved track of negligible friction, as shown in the figure. The potential energy U of the object as a

function of the position x is shown in the graph. The object starts at rest at x=0. Which of the following is a correct claim about the motion of the object?
(Would prefer an explanation, but it's not necessary)
A) The kinetic energy of the object is approximately the same at x=2m and x=5m.

B) At x=2m, the object has more potential energy than kinetic energy.

C) The object comes to rest when x=5.5m.

D) The rate of change of the potential energy is a minimum at x=0m.

E) The object achieves its maximum speed at approximately x=3m.
