The figure shows a graph of electric potential versus position along the Xaxis. A proton is originally at point A, moving in the positive X- direction. How much kinetic energy does it need to have at point A in order to be able to reach point E(with no forces acting on the proton other than those due to the indicated potential)? Points B, C, and D have to be passed on the way. C Electric potential at A is 104.2 V, at B is O V, at Cis 60.0 V, at D is 142.9 V, and at Eis 55.0 V. :J
