A uniform electric field exists in a region between two oppositely charged plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate, 2.0 cm away, in a time 1.5 X 10^-8 s. (a) What is the speed of the electron as it strikes the second plate? (b) What is the magnitude of the electric field E?

wouldn't the final velocity be zero since it hits the plate? If you are trying to find the velocity right before it hits the plate shouldn't you use a time that is slight smaller than the one given, since it describes the time for it to hit?

Where did you get the mass from? In part two?
