Solve each part of given problem:

Problem: An electron is released from rest in a vacuum between two flat, parallel metal plates that are 9.0 cm apart and are maintained at a constant electric potential difference of 620 Volts.

Part A: If the electron is released at the negative plate, what is its speed just before it strikes the positive plate?

Part B: What is the kinetic energy of the electron in units of eV?

I need the right answer and steps of solving this problem. Thanks!
