How Fast Does an Electron Travel in a Weak Electric Field with Gravity?

[somebodyelse5]

Homework Statement

An electron is released from rest in a weak electric field given by vector E = -2.40 10-10 N/C jhatbold. After the electron has traveled a vertical distance of 1.8 µm, what is its speed? (Do not neglect the gravitational force on the electron.)

Dont even know where to begin.

Steps to consider:
whats the force on the electron due to the E field?
what about due to gravity?
Whats the net force?
How can you use that information?

do you know of any good online physics resources for electro fields? I am having some trouble understanding everything the professor is teaching, and i know this stuff should be much easier than i am making it!

I would find the acceleration of the electron. Then look at your kinematic equations
