I don't have a copy of the graph, but

A = 100 V

B = 0 V

C = -60 V

D = -20 V

E = 55 V

Okay so I know that since positive charges move through decreases in potential, and the potential and potential energy are greatest at A, the proton will spontaneously travel from point A to point E. So, Ka = 0.

But I'm really not sure how to calculate the kinetic energy for the electron. If someone could help me out, I'd appreciate it!!!
