Your best friend wants to run a 5K with you next year. You are terribly out of shape, so you want to slowly start training to be ready! A 5K is five km, and you have decided to break this distance into smaller amounts that you will use to help you train and meet your goal.

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
